I made a rag quilts a couple of years ago. I did not wash fabric until quilt was completely sewn and clipped my was queen size and then as was suggested I went to a local laundramat (where a large industrial type washer were available) I washed and dryed my quilt there. Was I ever glad I did. There was a huge amount of thread and lint…I would not have wanted all that in my home washer. Much easier to clean at laundramat
