I have made 3 rag quilts,mostly with material I have found in thrift store. I have also bought the thicker flannels sheets from the stores. I havwe prewashed all of the flannels pieces I havve used in the quilts and still have great fluffing when I have washed them twice after finishing. I have bought flannels from Hobby Lobby only once and it was a demin looking one. I had no problems with it.
