Sun printing sounds magical, and the best part is it actually is. You lay a leaf on treated paper, let the sun do its thing, rinse it in water, and a permanent blue image appears in minutes. The real challenge is picking a paper that delivers a rich, even blue instead of a pale gray shadow, especially when the sun is weak or the coating is thin.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Here is your shortlist of the best cyanotype paper options, ranked by real-world success for kids, classrooms, and crafters.
Our Picks at a Glance
How To Choose The Best Cyanotype Paper
Sun print paper all works the same way, but the results vary wildly between brands. The paper is coated with a light-sensitive solution that turns blue where sunlight hits it. Objects placed on top block the light, leaving a white silhouette in the middle of that blue field. The price, sheet count, and paper size are easy to compare, but chemistry and coating consistency are what actually decide your print quality.
Exposure Time and Sunlight
Direct sunlight is non-negotiable. Cloud cover scatters UV light and leaves you with a faint image that rinses right off. In a strong midday sun, some papers need only 1-2 minutes, while others recommend 5-15 minutes. Your local latitude and the season change the math, so budget a little trial and error on your first few sheets.
Sheet Count and Sizes
Think about what you are making before you count sheets. A 40-sheet pack at 5 x 7 inches is perfect for quick practice and travel souvenirs. Bigger projects like framed botanical art eat paper fast, so a 100-sheet pack with mixed A4, A5, and A6 sizes gives you flexibility for everything from postcards to larger prints. More sheets usually means a lower cost per print, but only if the coating works.

In‑Depth Reviews
1. Nature Print Paper NPP40
Our pick — over 4.5★ from 550+ verified ratings; the strongest balance of quality and price.
The classroom crowd-pleaser that turns a sunny afternoon into a permanent keepsake.
The thing everyone raves about is how much pure fun this paper delivers — it is the top reason owners pick it, and it holds up beautifully for big groups like summer camps and science lessons. At 5 x 7 inches and just 4.5 ounces, it is light enough to toss into a travel bag, so you can press local leaves on a trip and bring home a framed memory instead of a suitcase of dirt.
The process is forgiving for beginners: place your object, expose to sun for 1-2 minutes, then slip the sheet into a tray of tap water for a minute and blot dry. Florida buyers report the solar math works out to a quick 1-2 minute exposure, and the water rinse reverses the colors for a fun second reveal. The exposed areas turn a rich blue while unexposed spots stay white, with middle tones showing up as lighter shades of blue.
It is biodegradable and uncoated, which keeps the eco-footprint small. The honest trade-off shows up in the details: the blue is not the deepest navy you will ever see, and the paper runs thin, so it curls if you lay it flat to dry. For most kids, classrooms, and casual crafters, that is a fair price for a pack that reliably works on the first try.
What wins people over
- Consistent, easy results for kids and big groups
- Travel-friendly at 5 x 7 inch and 4.5 ounces
- Plexiglass sheet included to hold objects in place
- Biodegradable paper
Worth knowing
- Blue comes out lighter than deep navy
- Thin paper curls when dried flat
- Final blue tone takes hours to fully settle
Reach for this if: you want a dependable, low-cost pack for groups, kids, or travel souvenirs.
Look elsewhere if: you need gallery-depth blues or heavy paper that lays perfectly flat.
2. mwellewm 30 Pcs Cyanotype Kit
The entry-point kit that includes everything you need to fall in love with sun printing.
If you want to dip your toe into cyanotype without buying a chemistry set, this is the kit. The package includes 30 sheets of A5 paper, 1 acrylic board, 10 clips, and a piece of twine, so you can start printing the moment it arrives. Flowers, die cuts, and stencils all come out clean on the first try, which is why owners describe the hobby as addictive.
The paper is made from a sturdy blueprint material that resists tearing, and the A5 size sits at a comfortable 5.8 x 8.3 inches — big enough for real projects, small enough to carry anywhere. The maker notes the paper performs best within 6 months of purchase and should be stored away from light, so buy it when you are ready to use it. The catch is direct sunlight: owners mention the image rinses right away if clouds roll in, and the fix is a firmer 3-5 minute exposure in full sun before you rinse.
For teachers, this is a standout because students can run the whole process on their own, from picking leaves on a nature walk to watching the print develop. It also beats the top pick on accessories — the acrylic board and clips are extras you would otherwise buy separately.
Best for beginners: the kit removes all the guesswork about what else to buy, and at 30 sheets it is a low-risk trial.
One honest note: it only works in direct sunlight, so a cloudy day means waiting or rescheduling your session.
3. Eersida 60 Sheets Cyanotype Paper
A budget bulk pack with 60 sheets, compared to the top pick’s 40 sheets.
At 60 sheets, this pack has 60 sheets versus the Nature Print winner’s 40 sheets. — so it is the obvious choice when you have a whole class or a long craft session ahead. The paper measures 5.8 x 8.3 inches, a touch larger than the top pick’s 5 x 7 inch sheets, and the glossy finish makes it feel more substantial in the hand.
It is built for group settings like classrooms, camps, and libraries where kids can press plants under a glass pane and watch the blue form. The recommended process is 5-10 minutes of sun exposure followed by a 1-minute rinse, and owners confirm it works great for kids when you hold the objects down with picture-frame glass. It is biodegradable and resistant to tearing, so it survives the chaos of a busy craft table.
The mixed feedback is real and worth knowing. Some owners in strong sun report disappointing results — one called it “a pathetic item” after a faint shadow failed to develop even after 25 minutes in Arizona sun. The recurring gripe is the lack of any instructions, which led one grandparent to ruin the first few sheets trying to find the treated side. Treat this as a budget-friendly bulk option for sunny days and simple projects, not a guarantee of rich indigo tones.
The straightforward read: you get the most sheets for the lowest cost, but expect lighter blue tones and bring your own knowledge of which side is coated.
Who it suits: high-volume users who want lots of practice paper and accept an occasional dud in the stack.
4. BBTO 100 Sheets Cyanotype Paper
One hundred sheets in four sizes, ready for everything from postcards to full-page art.
This is the pack for people who do not know yet what they want to make. It arrives with 30 sheets of A5 (5.8 x 8.3 inches), 30 sheets of A6 (5.8 x 4.1 inches), 10 sheets of A4 (8.3 x 11.7 inches), and 30 square 4 x 4 inch sheets — a mix that covers tiny gift tags, standard postcards, and larger framed pieces in one box. The paper is a sturdy blueprint material that resists tearing and deformation, and the images should not fade over time when you use the kit properly.
The matte finish suits a wide range of projects, and the process is the same familiar recipe: place leaves or paper cuttings, press with glass or acrylic, expose for 5-10 minutes in the sun, rinse for about 1 minute, and let it dry. Objects that block the sun show up white while the rest of the paper turns blue. One catch is that the transparent glass or acrylic sheet is on you — it is not included — and the directions are vague enough that most owners check online videos before their first session.
Buyers love it for kids’ projects and science classes, noting the color develops nicely with just sunshine and a water rinse. The honest downside is quality control: a few customers note sheets that tear during rinsing or some pages that do not develop evenly, and one notes plain water alone did not trigger the full blue reaction. For the sheet count and size variety, though, it is a strong value for mixed-purpose crafting.
Why it stands out
- 100 sheets across A4, A5, A6, and 4×4 sizes
- Sturdy, tear-resistant blueprint paper
- Images resist fading over time
Before you buy
- No glass or acrylic sheet included
- Directions are vague — plan to watch a video
- An occasional sheet tears or develops unevenly
Pick this for: anyone who wants variety — small squares for cards, big A4 sheets for wall art, all in one order.
skip it if: you want a single consistent size or a kit with the pressing plate included.
5. Spakon 32 Sheets Cyanotype Paper
The biggest standard sheets in this lineup, made for adults who want a full-page canvas.
If the 5 x 7 inch sheets feel cramped, this is your upgrade. Each sheet measures 8.3 x 11.7 inches — roughly a full A4 page — while the Eersida pack’s sheets are 5.8 x 8.3 inches. That extra room matters when you are arranging a large fern frond or laying down a printed negative for a serious botanical print. The paper is thick and sturdy, holding up to handling better than the thinner budget options.
The process asks for about 10 minutes of direct sun, then a rinse under the tap and a couple of minutes to dry. It is a favorite for homeschool co-ops and adult craft groups because the smooth finish takes a clean image and the size gives everyone room to compose. The most useful tip from owners: make sure your object cannot blow away and that there are no shadows across the paper, because any shade becomes part of the print.
The gamble here is batch consistency. Reviewers point out a first batch that printed beautifully with excellent coating, then a second batch where half-size sheets were poorly coated. A few also note the paper creases easily, and any fold ruins the print because the crease becomes a permanent line. For adult crafters who want large-format results and are willing to test a sheet or two first, the payoff is rewarding.
The big-canvas argument: at 8.3 x 11.7 inches it leads the list for print size, giving adults real room to compose.
The caveat: coating quality varies between batches, so budget your first sheet as a test run.
6. Jacquard Cyanotype Kit
The complete chemistry-set approach, for when pre-coated sheets are not enough.
This is a different beast from the rest of the list. Instead of pre-coated sheets, you get pre-measured chemicals (Part A and Part B), high-quality fine art paper, a glass printing frame, a professional-grade hake brush, SolarFast Film, a film marker, and clips — everything needed to coat your own surfaces. That means you can print on paper, fabric, wood, silk, or linen, which no other pick here can do. The images are archival, lightfast, and fade-resistant, though wearables will fade with washing.
The process takes longer and rewards preparation: mix the chemicals with water, brush them on your surface, let it dry, arrange your objects or negatives, and expose to sunlight or UV. After exposure you rinse with cold water to reveal the rich, deep blue tones. Owners say the instructions are clear and the kit is genuinely kid-friendly, yet the quality satisfies adults, with one young artist progressing quickly from random items to a composed forest scene. The glass printing frame keeps your objects flat, which solves the blowing-leaf problem that plagues outdoor printing.
This is the premium end of the spectrum, and it is worth every extra step if you want control over the output. You can prepare treated materials ahead and store them in a dark place until you are ready to print, and the included SolarFast Film lets you turn any photo into a photographic negative. The trade-off is that it is a project, not a quick activity — you mix, coat, and wait for drying time before the sun even gets involved.
The professional edge
- Prints on paper, fabric, wood, silk, and linen
- Glass printing frame holds objects flat
- Pre-measured chemicals remove the guesswork
- Archival, fade-resistant results
The commitment
- Requires mixing and coating your own surfaces
- Drying time means it is not instant gratification
- Wearables fade with washing
Choose this for: artists and serious hobbyists who want to experiment across surfaces and control the chemistry.
Pass on it if: you just want pre-coated sheets for a quick afternoon craft with the kids.
Understanding the Specs
Sheet Count vs. Price Per Print
Sun print paper is priced by the bundle, so the sheet count determines your real cost per finished image. A 40-sheet pack works out cheaper per print than a 30-sheet kit, and a 100-sheet pack stretches further still. But more sheets only helps if the coating actually develops — a cheap pack with inconsistent chemistry costs you more in wasted projects.
Paper Size and Format
Size dictates what you can make. Standard prints run 5 x 7 inches for practice and travel, while A4 (8.3 x 11.7 inches) suits full-page botanical art. Kits with multiple sizes, like the BBTO pack, let you experiment with postcards, tags, and large pieces without buying separate boxes. Bigger paper costs more per sheet, so match the size to the project.
