What projects did you do in this technique? Hats, gloves, scarves, socks?
I did bookmarks to learn how to doubleknit and several potholders. Knitting potholders in this technique with cotton yarn results in really good isolating due to the resulting thick fabric.
What I want to try in near future is to use this technique for fingerless gloves. Im thinking about the free pattern "Cheesehands" by Julia Mueller. There is also a matching hat available, called "Cheesehead".
