What a novel idea -- using dryer lint to make crafts! Here are a couple of recipes you may find useful if you want to make small figurines and ornaments. You may need to make a few adjustments to tweak for consistency, but here are the basics to get you started:
2-3 cups lint
soaked in 2 cups of water over low heat.
Slowly stir in 2/3 cup of flour. Cook, stirring constantly over low heat. When the mixture holds together, turn it out onto several thicknesses of old newspaper. Let cool.
You can mold this into small shapes. It behaves like a mouldable paper mache.
If you want something with a consistency more like clay, mix your 2 cups of lint with 1/3 cup water, 3/8 cup of white glue, and 1 T clear dishwashing liquid. You can add food coloring or a little tempera paint at this point. Knead the concoction until you get the consistency you want.
