AnngelAnne I have zigzagged edges before washing as well as using pinking scissors on the edges. Both have worked well and pinking scissors are quicker. I know some people use a washing bag for small pieces as well. I don't use much in the way of precuts. Fat quarters usually the smallest. When I have a charm pack I just use it as is.
Ok sounds like fun and I hope if you fall you let us see pictures of the fabric.
