While this isn't knitting at its finest, I can totally see the meditative draw of doing it now. Leftover skeins of tapestry wool went into the road trip craft bag. I ran each color through the knitter until there wasn't any left. (Note: 18 inches of tapestry wool = about 1 inch of knitted tube) The book called for specific sizes on some and for those I stopped at the required length. These are still waiting to be turned into something.
I'm also wondering if I couldn't make even smaller tubes using crochet thread and a homemade knitter from an old thread spool with nails on one end. They might make cute necklaces or bracelets.
