As a group project, my weaving group undertook to make a friendship quilt. Each weaver wove 12 squares using the same warp on their loom, but using different yarns for the weft - each person gave everyone else some of their own yarn. Some people used cotton, other used wool, or blends. I used handspun wool, in a mixture of blues and jacaranda/purples. You then give each person the piece you wove with their weft yarn. I am still waiting for a couple of people to complete their squares, and then I will create an interesting quilt or some such item with the squares. Since everyone wove a different pattern, the squares will all be similar but different.
One of the girls who participated is totally blind. She wove her squares all by feel. Amazing woman.
