The last rag quilt I made was of 3 layers of flannel. Turned out great, but when I washed it in my washer, all of the 'debris' ended up between the inside and outside drum. This would not allow the tub to spin out. Had to call a repairman to come work on it. Lesson learned. I love rag quilts but because of this will probably not make any more of them. We do not have a laundromat here.
