Secure window screen over a picture frame with duct tape.
Blend ripped-up paper, plant materials, and water until your blender is full and you have a smooth, thick paste. Let it set for two minutes.
Mix 4 inches of water, 2 tablespoons of white glue, and the paper mixture in a large tub. Add leaves, flowers, or seeds to personalize your paper.
Scoop the frame under the surface of water and slowly lift. Repeat if the screen is not covered evenly. Allow the water to completely drain out.
Place the frame with the paper mixture in a dry spot. Once the paper has dried, carefully remove it from the frame.
Use an iron, on the hottest setting, to steam out your paper. Your handmade paper can be used in a variety of fun and useful projects.
