jI would not trust any type of colored felt not to fade when washed and I don't think it is really sturdy enough for heavy washing, maybe for a wall hanging that won't be washed much, if at all. I would use sheet blankets if you can find them, light blankets, washed flannel, acrylic fleece, good used sheets of either cotton or flannel, etc. Check your thrift stores to see what you can find. Sometimes you can hit the jackpot.
