I'm going through my shelves, organizing the yarn I have, trying to tidy an take inventory, so I don't buy something like what I already have, and I have a steadily growing mound of what I call "Demons": Yarn that I don't like, won't use, and have no idea how it came to be in my possession. (Sale I couldn't pass up? e-bay lot buys? gifts?) What are you all doing with the monsters in your collection? Should we try an online yarn exchange?
