My thanks to all of you for your input. I am leaning towards a commercial laundry since our pipes are small and I'm afraid might plug up. A lot of good info here. Years ago, I made one using homespuns and flannel....It shed A LOT so I've never wanted to make one again......This one is going to be a twin size so I'm thinking use the commercial to wash and maybe dry at home......

I hang a lint sock on the hose coming from the washer into the sink and it catches a ton of stuff. So, no drain clogging worries. I've always done my rag quilts at home--too lazy to go out! and, I've done a full-size that way without any problem. I do check my dryer partway through the drying cycle too.
