I've made a few. Made a couple of baby ones out of flannel and a couple of twins out of homespun. The ones I've been able to keep track of (my son's homespun and grandson's flannel) have both held up well through at least a couple of washings each. I love making rag quilts, except for the clipping :) Have arthritis in my fingers and the clipping nearly kills my hands. It takes nearly as long to clip the seams as to make the whole quilt! I saw a guy do one on Fons and Porter and he used a weed whacker to get the fraying done. Looked a lot faster and he swore it wouldn't harm the blocks.
