We created unique weaving patterns.
The Harrisville Designs 7" Potholder (Traditional Size) Loom Kit is my favorite tool for teaching weaving. When the kids are finished weaving the loops over and under they have a usable potholder to keep for themselves or give as a gift.
Recently, we began creating new potholders with slightly more difficult designs. When patterns are created going over two loops and under one, instead of the basic over one, under one sequence, new and beautiful patterns begin to emerge.
The Map is Not the Territory blog displayed a similar activity which used paper instead of potholder loops as the medium. Be sure to visit for more pattern ideas.
