if you want to destroy my sweater

[warheart.livejournal.com]

i just recently got a bunch of sweaters that someone was throwing away at the end of their garage sale (score!) and i remember seeing a tutorial on this community for unravelling sweaters. i think it was this community anyway.
i looked in the memories under a few different categories that i thought it would be in but i didn't see it anywhere. can someone link me to either that, or another tutorial on how to unravel? or kindly explain? thanks.
