A sun print bookmark is the kind of project that makes a kid gasp. You lay a fern leaf on special paper, wait in the sunshine, rinse the sheet under the tap, and a pure white silhouette appears on deep blue.
This one started with a muggy week, a spare-room craft table and a vent blowing straight across the drying prints. When the air in your craft corner is the problem, what should you ask when looking at Air Duct Cleaning Naples? We’ll come back to that below. First, the project: about an hour start to finish, and most of that is waiting.
What you’ll need
- Pre-coated sun print paper, sold in craft stores and toy aisles (a sun print kit works too; follow the label)
- Flat things from around the house: fern or clover leaves, feathers, lace scraps, paper clips, a paper snowflake (anything that lies flat and blocks light)
- A clear plastic sheet, plus a clipboard or cardboard to lay the paper on (the cover from a plastic report folder works fine)
- A shallow tray of plain tap water (a clean washing-up bowl)
- Paper towels and a heavy book
- Kid-safe scissors, a hole punch and some ribbon (a shoelace, even)
Set up your space
This is a low-mess project, but water and kids find each other. Put a towel under the rinse tray, keep a wipe-down station (one damp cloth, one dry) by the table, and hand out old shirts, including one for the grown-up.
You need two spots: a dim one for arranging and a sunny one for printing. The paper reacts to daylight, so keep it in its sleeve or a dark folder until you’re ready. A hallway with the curtains drawn suits the first job, and a sunny windowsill, porch step or patch of yard suits the second.
Then think about where the wet prints will dry. Damp paper dries slowly in a muggy room, and a vent or fan blowing straight across it curls the corners before the middle is dry. Pick a flat surface with gentle air and no vent pointed at it. If dust keeps landing on wet work or the airflow in your craft corner still feels off after you move the table, that’s a question for a licensed heating and cooling professional. A good one will explain what they plan to inspect, what the job involves, and how they’ll protect the room, so cover or move your supplies before anyone arrives. Leave vent covers and ductwork to them.
Step by step
Step 1: Collect and test your shapes (about 15 minutes)
Let each kid fill a small box with flat treasures. The best shapes have a clear outline: a feathery fern, a maple leaf, a key. Lay them on scrap paper first, in the dim spot, to plan the picture.
When it’s right, you can read each shape at a glance. The common slip is a leaf that’s thick or curled, which leaves a blurry edge. Press it in a heavy book for a few minutes first, and it will behave.
With kids: Younger children can sort shapes into “good shadows” and “mushy shadows” while you check them. Older kids can plan a border or a pattern.
Step 2: Arrange the shapes on the paper (about 10 minutes)
In the dim spot, slide one sheet of sun print paper out of its sleeve and set it blue side up on the clipboard. Place your leaves and feathers on it, then lay the clear sheet over the top and clip it down. Keep the other sheets in their sleeve while you work, because one stray sunbeam will pale the whole stack.
When it’s right, every shape touches the paper wherever you want a sharp outline. Anything that floats above the paper prints soft. The other slip is a breeze lifting a feather on the way outside, so carry the whole board flat, like a tray of cookies.
With kids: This is the best kid step. Let them choose where each shape goes, then sit on your hands and let the picture be theirs.
Step 3: Expose it in the sun (a few minutes)
Carry the board into direct sun and set it down flat. Check the package for timing, because papers differ. The blue will lighten to a pale, washed-out shade, and that’s your signal.
Clouds don’t ruin anything; they only add waiting time. Don’t lift the clear sheet to peek, since moving a leaf mid-print leaves a ghost double outline. Once the color has faded, carry the board back to the dim spot.
Step 4: Rinse it clean (about 2 minutes)
Remove the shapes and slide the paper into the tray of plain water. The pale blue turns deep and rich while the white shapes stay crisp. Swish gently, following the label’s timing.
The common slip is stopping too soon, which leaves a muddy, streaky print. If the water still looks cloudy, change it and rinse again. Kids love the swishing, as long as a grown-up carries the tray.
Step 5: Dry it flat (about an hour)
Lift the print out by its edges and lay it on a paper towel. Cover it with a second towel and put the heavy book on top. Paper that dries under weight stays flat, and humid rooms need that help most.
When it’s right, the print feels cool and dry all the way through, with no soft patches. Dry it flat and away from any blowing vent, since a draft curls the edges into a taco. If one does curl, dampen it lightly and press it under the book again.
Step 6: Trim and punch (about 15 minutes)
Mark a bookmark shape on the white back with a ruler and pencil, then trim with kid-safe scissors. A grown-up can cut larger sheets down to size beforehand, because long straight cuts are fiddly for little hands.
Punch a hole in the top and loop through some ribbon. The slip is a hole too close to the edge, which tears. Leave a thumb’s width of paper around it.
With kids: Little ones can decorate the white back with markers while the print finishes drying. Bigger kids can write a message there for whoever gets the bookmark.
Finishing and display
Bookmarks are the easy win: tuck them into library books, slip them into birthday cards, or tie them to a gift. For something bigger, print a full sheet and slide it into a simple clip frame.
Like any paper art, sun prints like a dry spot out of long stretches of bright light. In a damp climate, keep finished pieces somewhere airy, never in a cupboard against an outside wall. A row of prints on a string with clothespins makes a cheerful, changeable display.
Try it this weekend
The smallest version is one sheet, one leaf and one sunny windowsill.
- Time: about 20 minutes of hands-on work, plus drying
- Supplies: one sheet of sun print paper, one leaf, a clipboard, a bowl of water
- The step that matters most: pressing the leaf flat under the clear sheet
Where to take it next
- Another medium: trace the same leaf shadows on plain paper with pencil in window light, then color them in with watercolors.
- A bigger group version: have everyone in the family make one print, then tape them in a grid on a wall for a blue-and-white patchwork.
- A seasonal series: collect one leaf a week for a month and print each one.
However your first sheet turns out, you’ve made something with sunlight, and that’s worth taping to the fridge.
