My oldest daughter found a whole stack of counted cross stitch I had boxed up for years, and she backed them with fusable inerfacing and sewed them into a memory quilt for her two girls. they came out real nice and she has washed them several times. She uses woolite was and hangs them to dry. Hope this helps. Whatever you do, DONT THROW THEM AWAY!
Never discard your handy work. I think there must be a law against it ...LOL
