Only two people (that I am aware of) took me up on that invitation. This morning my Canadian friend Elaine sent me a photo of hers and I was waiting for it before making this post. Elaine said she used mostly leftover yarn, wool, sari silk and sweaters. If you tap on the photo you will see how the various textiles compliment each other. Great job Elaine and like the colors you chose.
I'm definitely going to try using different textiles in a future rug but have so far avoided spending money for sari silks. Guess I could always cut up silk blouses but they don't have the varying colors of sari.
You may already have seen Lauren's Cat's Paw on her blog a few weeks ago. Lauren designed her piece to fit the seat of her newly inherited rocker. She also used up some of her worms but said it wouldn't make a dent in them.
