I do and I love them especially when I have a Tendonitis flare and can't crochet or spin.I have made lots of things on them and will be teaching myself cables next.Normal knitting makes my finges ache badly and is frustratingly slow for me as well as i can't unravel and re do my mistakes as easily as crochet. So for me the KKs and Looms are fantastic.
Knifty Knitters are yes looms pretty much here's a pic of the round looms they are very easy to use and are great! Even though I'm only 13 (turning 14 in 29 days!) My hands start to ache when I knit normal after like 15-30 min so I use these instead! Here are the long looms that you can make scarves and shawls pretty much anything!
You can get then at Wal-Mart for around 12.00 for a set of the round ones and about 20.00 for the long ones! You should try them out sometime!
I also have a smaller flower one and a still smaller one. I've whipped up a couple of quick scarves on the flower one. I want to make school color scarves out of my Yarn Bee Airy yarn before football season for wither other cheer moms or Booster Club and I htink I can crank them out with that.
