things to do with yarn

[savethepirate.livejournal.com]

ive searched the memories, and i couldnt find anything, so i figured its safe to ask here (if ive completely missed something and you just point it out i can delete this entry). i was wondering what things you can do with yarn other than the regular crochet/knitting. i remember doing arts and crafts when i was younger with it, things like dream catchers and those pictures you would make with yarn and glue, but is there anything else? preferably something less little kid-ish, but actually i really want to know all possibilities! thanks so much!
