I love making rag quilts, in all sizes and with either cottons or flannels. However, I just wet the seams when it's all clipped and run it thru my home dryer 3-4 times, re-wetting it each time until the lint trap isn't full. I do have to empty it several times during each cycle which is a pain. The local laundromat has a big sign up that says, simply.. "Absolutely NO rag/frayed quilts!!" so that leaves me with no place to wash and dry it those first few times.
