I have made several rag quilts. I have an old king size sheet that I have folded in half and stitched up both sides and I put the rag quilt in it and stitch up the opening. I can then wash and dry the quilt in my washer and dryer. Once it comes out of the dryer I unstitch part of the seam and take the rag quilt out and shake. Do this outside because threads are everywhere.
