Wonderful find! My little sis just told me the other day to go to the thrift store and buy some wool sweaters and wash them on HOT to make some really nice boiled wool looking fabric for crafting. There is a tiny thrift store here but I think summer is the time to find sweaters. Right now people are actually wearing them (its a balmy 22 right now). I don't live anywhere near a fabric store or crafting store to buy any. Great stash you ended up with.
