Gather the wet-work tools
Set up where spills are easy to wipe. You will need scrap paper without tape, a bowl for soaking, a blender, a large tub, a flat screen held in a frame, a sponge, and absorbent towels or felt. The American Museum of Natural History's illustrated method shows how to make a simple frame from a shallow pan and screen if you do not own a paper mould. Check it before cutting anything; the pan edges and tools can be sharp. Children need an adult for cutting and blending.
Make a thin pulp
Tear the paper into small pieces, remove tape, and soak it in warm water for at least thirty minutes. The museum suggests about one and a half cups of dry scraps for a sheet. Blend a handful of soaked pieces with enough water to move freely, with the lid secured, until you have a loose pulp. Work in small batches and follow the blender's directions. Colored scraps will influence the final sheet; the blue pulp in the photograph is one possibility.
Lift and dry a sheet
Put water in the tub and lower the framed screen into it. Pour the pulp over the screen and move it gently until the fibers form an even layer. Lift it level and let water drain back into the tub. Blot with a sponge, then transfer the damp sheet onto a towel or felt, following the museum's photographs for the careful flip. Press it between absorbent layers and leave it flat to dry. Drying may take hours or longer depending on the thickness and room. Peel the sheet away only when it is dry.
If the sheet tears during transfer, use a little more pulp and press out more water next time. If it dries too thick to fold, use less pulp. Strain leftover pulp into the trash or save it for another batch; the museum advises keeping it out of the drain.
Give the next sheet a purpose
Use a dry sheet for a short note, a gift tag, or a page in a notebook. For texture, the museum suggests stirring in small pieces of dried flowers or herbs before forming the sheet. Start with just a few fully dry petals, perhaps from flowers you pressed in a book, and see how they settle in the pulp. The photographed paper shows the making process, not petals in the finished sheets.
I hope this finds you well,
