Pressing flowers in a book looks almost too simple. Put a flower between pages, close the book, wait, and hope for the best.
That basic idea works. The details decide whether you end up with a beautiful pressed bloom or a damp brown shape permanently attached to your favorite hardcover.
For brides, the stakes can be higher. You are not pressing random daisies from the backyard. You may be working with the rose you carried down the aisle, a piece of delphinium from your wedding bouquet, or flowers tied to someone you love.
The good news is that book pressing remains one of the easiest and least expensive ways to preserve flowers at home. Botanical institutions use the same basic principles on a more controlled scale. You need to remove moisture quickly, keep the flower flat, apply even pressure, and give it enough time to dry completely. The Natural History Museum, Royal Horticultural Society, and University of Florida Herbarium all describe pressure plus moisture removal as the foundation of successful plant pressing.
This guide shows you exactly how to press flowers in a book, which wedding flowers work best, how long to leave them, how to prevent mold and browning, and when your bouquet deserves professional preservation instead.
How to press flowers in a book step by step
What you need before you start
You do not need a flower press to press flowers.
For the traditional book method, the Royal Horticultural Society recommends heavy hardback books and layers of kitchen paper or tissue paper. Its instructions call for three or four heavy books, with hardbacks over 500 pages working well.
Gather these supplies:
- A large, heavy hardcover book that you do not mind potentially staining.
- Plain absorbent paper such as blotting paper, plain tissue, kitchen paper, or newspaper.
- Several additional heavy books.
- Clean scissors.
- Fresh flowers that feel dry on the surface.
- Tweezers, optional but useful for delicate petals.
- A note with the pressing date so you do not forget when you started.
Do not use a sentimental first edition, your wedding guest book, your childhood copy of Harry Potter, or anything you would be devastated to damage.
That warning is not theoretical. Brides discussing DIY bouquet pressing on Reddit have reported both successful book pressing and ruined books caused by flower moisture. One bride said her attempt “ruined some of my favourite books.” Treat the pressing book as a piece of equipment.
The safest setup puts absorbent material between the flower and the actual book pages.
Botanical institutions take moisture management seriously for a reason. The University of Florida Herbarium describes blotter paper as the moisture absorbing component of a traditional plant press and says the goal is to remove moisture quickly but gently while preserving the plant's structure.
The book pressing method
Start with the freshest flowers you can.
For wedding flowers, that usually means beginning as soon as practical after your celebration rather than letting the bouquet sit in a warm hotel room for several days. Professional herbarium guidance recommends pressing plant material promptly because petals and leaves begin wilting and changing shape after cutting.
First, check the flower.
It should feel dry on the surface. Do not press a rose covered in vase water, a flower still damp from rain, or a bloom that has started getting slimy.
Remove damaged outer petals. Trim excess stem. Remove obvious pollen if it could stain pale petals.
Then decide whether the flower can realistically lie flat.
A violet can.
A daisy can.
A small cosmos can.
A fully open garden rose with 60 tightly packed petals cannot behave the same way.
For a thick flower, you may need to remove the stem, separate petals, divide the bloom, or press selected parts rather than crushing the entire flower intact. University of Florida herbarium guidance specifically notes that bulky plant structures may need to be cut or dissected before pressing.
Now open your book near the middle.
Lay down at least two sheets of absorbent paper. The RHS book method calls for two sheets below the flowers and another two sheets above them.
Position the flower exactly how you want it to look.
This matters.
Once you close the book, a folded petal stays folded. A crooked stem stays crooked. Two overlapping flowers can dry together.
Spread petals gently. Straighten leaves. Turn the flower face forward if you want a traditional botanical look. Place a few petals sideways when you want more dimension in a future design.
Leave space between flowers.
Then cover them with your top sheets of absorbent paper.
Close the book slowly.
Do not slam it shut. A quick close can move petals, bend stems, or fold the flower in half.
Place two or three heavy books directly on top. You want firm, even pressure across the entire area.
Natural History Museum botanist Fred Rumsey gives one of the most useful rules for the entire process:
“You want to ensure that you keep an even weight across the whole plant specimen that you're pressing.”
Uneven pressure creates wrinkles and shriveled areas.
Move the stack somewhere dry with decent ventilation. Avoid a damp basement, steamy bathroom, sunny windowsill, or hot car.
Then wait.
The Royal Horticultural Society's book pressing instructions recommend two to four weeks for full drying. Floral professionals interviewed by Architectural Digest describe roughly one to two weeks for some thinner flowers, which shows why there is no single perfect number. Flower thickness, moisture content, paper, airflow, temperature, and humidity all change the drying time.
For an important wedding flower, two to four weeks is the more conservative expectation.
Do not remove it just because it looks flat.
It needs to be dry.
The best flowers to press and the ones that need extra work
Thin flowers give beginners the easiest win
Book pressing works best when moisture can escape quickly.
That makes thin, relatively flat flowers excellent starting points.
Architectural Digest's 2025 guide, based on interviews with professional floral artists, recommends smaller, thinner, open facing flowers for book pressing. Examples discussed by its experts include wildflowers, geraniums, coneflowers, daisies, and pansies.
For wedding bouquets, you will usually have the easiest time with flowers and greenery such as:
Pansies and violas press beautifully because they already have a flat face.
Small daisies and chamomile style blooms are beginner friendly.
Delphinium and larkspur florets give you delicate color without a thick center.
Individual hydrangea florets can create beautiful pressed compositions.
Fern leaves and delicate greenery are generally easier than thick succulent foliage.
Baby's breath can work well when separated into small sprigs.
Small leaves, herbs, and fine filler flowers often become some of the most useful elements when you later rebuild the bouquet as artwork.
A bridal bouquet does not need to survive as one flattened object.
In fact, the finished artwork often looks better when you press individual elements and recreate the composition afterward.
That is how pressed preservation becomes design rather than simply flattening a bouquet.
You can see the difference in Bouquet Casting Co's pressed wedding flower preservation guide and pressed flower gallery, where the final piece treats the bouquet as a botanical composition rather than a smashed version of the original arrangement. Bouquet Casting Co currently offers multiple frame sizes and custom arrangements built from individually dried and pressed wedding flowers.
Roses, peonies, ranunculus, and other thick wedding flowers
This is where DIY pressing gets harder.
Thick flowers contain more plant material and more moisture. Both increase the risk of browning, rotting, uneven drying, and permanently misshapen petals.
Architectural Digest botanical artist Penny Ann Schmidt advises against simply book pressing large flowers with thick layers. Floral artist Linda Ruel Flynn also identifies moisture heavy flowers such as ranunculus and lilies as blooms that can require pressing paper changes during the first 10 days.
Roses deserve special attention because brides search for them constantly.
Yes, you can press a rose in a book.
No, you should not expect a large garden rose to flatten like a pansy.
For a small single layer rose, you may press the entire flower.
For a dense bridal rose, consider removing damaged guard petals, cutting away some of the bulky base, pressing the rose in sections, or separating petals and reconstructing the flower later.
The same principle applies to peonies and dahlias. Their dense petal structure makes them harder to dry evenly. That recommendation follows directly from botanical guidance to reduce bulky plant structures before pressing and floral expert guidance that thick layered blooms perform poorly in basic book pressing.
Ranunculus look delicate, but they can hold more moisture than their papery petals suggest. Lilies also require care. Ruel Flynn specifically recommends changing pressing papers several times during the first 10 days for moisture heavy varieties such as these.
Orchids can be pressed, but they deserve testing before you commit your only wedding bloom. Their shape, thickness, and color response vary considerably between varieties.
When you have only one irreplaceable specimen, experimentation carries a real cost.
Practice first with a similar flower from a florist or grocery store.

How to stop pressed flowers from turning brown, molding, or ruining the book
Moisture is the real enemy
When flower pressing goes wrong, people often blame pressure.
Moisture causes many of the worst problems.
Flowers contain water. Your job is to get that water out before fungi, bacteria, and plant degradation turn the flower brown or rotten.
The Natural History Museum says rapid drying can help preserve flower color and recommends a warm environment that removes moisture without overheating the specimen. It also recommends newspaper because it is absorbent and has useful antifungal properties.
The University of Florida Herbarium describes the same principle in scientific collection terms. Pressing should remove moisture quickly enough to reduce degradation by microorganisms while maintaining the plant's structure.
So start dry.
If your wedding bouquet has been sitting in water, remove the bloom and gently blot any obvious surface moisture before pressing.
Do not wash it immediately before pressing.
Do not mist it.
Do not trap a dripping stem inside a book.
Use absorbent paper.
Avoid packing too many blooms into the same section.
Give thick flowers extra attention.
Keep the book in a dry room.
If you are working with flowers known to hold significant moisture, inspect the absorbent sheets during the early stage and replace damp ones carefully. Do not repeatedly peel and reposition delicate petals just because you are curious.
Architectural Digest's floral experts explain that damp flowers and poor airflow are major causes of mold. Ruel Flynn recommends changing pressing papers for especially moisture heavy flowers and using a well ventilated room with low humidity rather than shutting the press inside a closet.
That is a useful correction to the classic childhood method of hiding a flower inside a dictionary and forgetting about it until Thanksgiving.
Your flowers will change color
This is the part many DIY tutorials skip.
Pressed flowers do not remain frozen at the exact color they had on your wedding day.
They are real plant material.
White flowers can become cream.
Blush petals can darken.
Red roses can deepen toward burgundy.
Some blue and purple flowers retain impressive color, while others shift.
Greens can become muted.
The Natural History Museum notes that faster drying can improve color retention. Floral preservation experts interviewed by Architectural Digest also stress that color changes over time are natural and that sunlight can accelerate them.
Linda Ruel Flynn puts the expectation clearly:
“Flowers are living, breathing things. There really is no such thing as permanent. Colors will change over time.”
That does not mean preservation failed.
Natural aging is part of preserved botanical material.
Once your flowers are completely dry, keep them away from humidity and direct sunlight.
For framed work, UV protective glazing gives you another layer of protection. Bouquet Casting Co's current pressed flower frames use UV protected acrylic, and the company also offers color restoration for flowers whose dried color needs adjustment.
If color matters more to you than keeping every flower completely untouched, professional color restoration can create a more polished finished result.
DIY book pressing or professional wedding bouquet preservation
DIY pressing makes sense when the risk feels acceptable
Book pressing is genuinely useful.
It is cheap.
It is accessible.
You probably already own almost everything you need.
Architectural Digest estimated the basic book method at essentially no added cost when you already own the books, paper, scissors, and flowers.
Reddit wedding discussions show why brides like it. Some couples press selected wedding flowers themselves, place them in floating frames, and love having a personal craft tied to the wedding. Others decide professional preservation costs more than they want to spend.
DIY is a strong choice when you are working with extra flowers, garden blooms, Valentine's Day roses, anniversary flowers, a bridesmaid bouquet, or several wedding blooms you can afford to experiment with.
It is also a good choice when you enjoy the process.
There is something nice about opening an old book weeks later and finding the flower you intentionally saved.
But your decision changes when the flowers are irreplaceable.
A wedding bouquet is not a Michaels craft supply.
There is no second one sitting in a cabinet.
The Knot's latest published Real Weddings Study found that couples married in 2025 spent an average of $2,800 on wedding flowers, based on responses from 10,474 U.S. couples. The same report found that 70% of surveyed couples identified price as their top priority when choosing a wedding florist.
You do not need to preserve your bouquet because it cost money.
But spending thousands on florals makes it reasonable to think carefully before testing your first flower pressing technique on the most sentimental arrangement from the day.
A useful decision rule is simple:
Ask yourself how you would feel if the flowers molded.
If you would say, “That was a fun experiment,” DIY them.
If you would be heartbroken, hand them to someone who does this every day.
For brides making that second choice, Bouquet Casting Co is the best professional option in this guide based on its currently published combination of preservation formats, custom design process, shipping support, and finishing options.
Bouquet Casting Co offers professional pressed flower frames, resin keepsakes, and shadow boxes. Current pressed frames start at $475. The pressed frame process includes professional drying and pressing, custom composition, optional color restoration, and design mockups before the work is finalized.
The company also provides a prepaid shipping label with full preservation orders and offers complimentary mock designs with unlimited revisions for reserved preservation clients. A $75 preservation date reservation currently secures studio capacity and is credited toward the eventual order.
That makes professional preservation especially useful when your bouquet contains roses, ranunculus, peonies, orchids, hydrangeas, lilies, or a mix of thin and dense flowers that will not all respond to the same DIY technique.
You can also read Bouquet Casting Co's DIY flower pressing versus professional preservation comparison and flower pressing mistakes guide before deciding.
There is no problem with doing both.
Press a few spare stems yourself.
Send the main bouquet for professional preservation.
You get the hands on memory and the polished heirloom.
Frequently asked questions about pressing flowers in books
How long should you press flowers in a book?
Plan on roughly two to four weeks for the traditional book method.
The Royal Horticultural Society recommends leaving book pressed flowers for two to four weeks to dry fully. Some thin flowers can dry sooner. Floral experts interviewed by Architectural Digest suggest at least one to two weeks for certain thinner blooms.
Do not rely only on the calendar.
The flower should feel fully dry before you remove it for permanent display. A thick rose will generally need more drying attention than a violet.
What is the best paper for pressing flowers in a book?
Use clean, absorbent, non glossy paper.
The RHS specifically recommends kitchen paper or tissue paper for its heavy book method and blotting paper or newspaper for traditional flower presses. The Natural History Museum recommends newspaper because of its absorbency.
Botanical presses typically use blotter paper because its job is to pull moisture from plant material.
Parchment also appears frequently in modern craft tutorials and is recommended by several floral artists interviewed by Architectural Digest.
For a sentimental wedding flower, prioritize moisture removal and protect the book with multiple clean layers.
Avoid pressing flowers directly against coated or glossy book pages. Floral professionals note that uncoated, porous paper performs better for traditional book pressing.
Can you press roses in a book?
Yes, but the type of rose matters.
Small or single layer roses are much easier than dense garden roses.
For a large wedding rose, remove damaged petals and consider deconstructing the bloom or pressing sections separately. Professional botanical guidance recommends cutting bulky plant material when necessary so moisture can escape and the specimen can flatten properly.
Layered flowers can also separate from their stems as they press.
Practice on a similar rose before using the only copy from your bridal bouquet.
Can you press your entire wedding bouquet in a book?
Do not press the intact bouquet as one object.
Take it apart.
Sort the flowers by type and thickness. Press thin blooms, leaves, and filler separately. Deconstruct dense flowers as needed.
A bouquet contains flowers with very different moisture levels. Treating all of them the same increases the chance that wetter blooms will rot while thinner ones dry successfully.
Professional pressed bouquet artwork works on the same general idea. The flowers are preserved individually and later arranged into a finished composition.
Bouquet Casting Co's pressed preservation examples show how flattened wedding flowers can be rebuilt into custom wall art rather than simply preserving the original bouquet bundle in place.
How do you keep pressed flowers from turning brown?
Start with fresh flowers, remove moisture efficiently, and keep them away from direct sunlight after drying.
The Natural History Museum specifically notes that rapid drying can help preserve color.
Still, you cannot guarantee that a natural flower will keep its exact wedding day shade forever. Floral preservation professionals emphasize that preserved flowers continue to age and change color over time.
For wedding artwork where color accuracy matters, professional preservation gives you options that DIY book pressing does not. Bouquet Casting Co, for example, currently offers color restoration for faded whites, pinks, and other blooms as part of its preservation services.
Can you put book pressed flowers in resin afterward?
Yes, but only after the flowers are completely dry.
Moisture trapped inside resin can create preservation problems. The flower needs to finish drying before you move to another preservation medium.
Pressed flowers can work well in small resin projects because they are thin and easy to arrange. Botanical artist Penny Ann Schmidt told Architectural Digest that she uses pressed flowers in resin jewelry, noting that resin isolates the dried flowers from outside elements.
Wedding bouquet resin casting is more complex than placing one dry petal into a small craft mold. Large resin pieces require careful drying, placement, pouring, curing, bubble management, finishing, and long term material considerations.
For an irreplaceable bouquet, professional resin preservation is the safer route. Bouquet Casting Co offers resin flower preservation alongside pressed framing, so you can choose the finished format after considering how your specific flowers will respond.
The basic lesson is simple.
Pressing flowers in a book works.
Use fresh flowers. Keep them dry. Give thick blooms extra attention. Put absorbent paper between the flowers and your book. Apply firm, even pressure. Wait long enough.
And decide what you are willing to risk before you begin.
For a backyard flower or spare rose, grab a heavy book and try it.
For the bouquet you carried down the aisle, practice first. Then decide whether the DIY experience matters more to you than getting the most controlled finished result.
That distinction saves a lot of regret.
