Last Sat. QVC had a craft day I was disappointed they didn't show very many knitting items but they did have knitting boards. They showed how to use them and they seemed very simple. They had all kinds of things they made from them from sweaters to a double sided scarf.. Here is where you can a see a picture of just of them.
Not much help but I take it can be done they even showed hats and booties...

Editing cause that didn't work as a link if you go to www.qvc.com and punch in those item numbers they should come up
