While this is oodles of fun, it's taking way too long. I tried throwing them in a mesh bag and into the washer but after two agitation cycles, they hadn't felted any more than they already were. Following this site's advice, I'm going to try tieing them into nylons and throwing them back into the washer. I could use some advice if you have any. No progress on the quilt. I've been spending way too much time making these darn felted balls.
