Flannel as batting for rag quilt- prewash?
I would like to make a rag quilt with cotton squares and use flannel for batting - same size as the flannel squares. The look I am going for is a soft fluffy edge. I am not sure if I should prewash the flannel as it may effect the ragging...but then if I don't , i wonder if the quilt squares will be wonky when the flannel shrinks. Maybe I should use minky? Whatever that is! Please advise. Thanks
