Those things always intrigue me when I'm looking around JoAnns, I don't think I'd even have the first clue how to use one though hehe. I know my grandfather was big into knitting with things like that and using looms, but he's been gone for a long time... so sadly I can't ask him.
You will LOVE the KK looms. I bought the round looms since I wanted to make hats and socks. The circular needles confused me, lol. Sadly, I've been neglecting my poor knitting needles.
