Here are two great hobby videos teaching you how to use the long purple rectangular Knifty Knitter loom. These instructions will also work with rectangular looms other than the Knifty Knitter.
Like I said before loom knitting is a fun hobby. It is also a hobby or craft that is pretty easy to master with the right instructions. I know the instructions provided with the Knifty Knitter are not exactly great, but videos like this really help you to get the most out of your knitting looms. I will put some more videos up getting into the more advanced stuff soon.
