Great job! I've got a few old sweaters I was thinking of doing the same with. One cool thing is to take a wool sweater that's too big for you, wash it in hot water to "felt" it, and then you can cut it without having to worry about it unraveling. Make sense? Then you don't have to bind the edges if you don't want to.
that's a really good idea! i've been told that felting was easy, but i've never gotten around to trying it! maybe i will now!! because binding the edges is pretty much a pain in the butt! thanks guys for the positive feedback!
