I have made several rag quilts and just used my home washer and dryer. There is so much lint that comes off them that if I was going to make a quilt that was larger than lap size I would use a commercial washer and dryer. One thing I have learned is that after you get them all clipped and before you wash them put it in the dryer and run it a cycle dry. You can get a lot of lint off them that way and it will save your washer. Good luck and remember the closer you clip the nicer the ragging will look. I usually clip closer than 1/4 inch.
