I have a front loading washing machine and back in December I was making a flannel rag quilt for a SIL. After it was finished, I washed it and low and behold it stopped up my washing machine so bad I had to get a repairman out to unclog it. I bought this flannel from JoAnn's! Will never buy flannel from them again. I have used Connecting Threads and Moda before on rag quilts and never had a problem.
