If you have noticed, I have a list of favorite blogs that I enjoy reading. On that list is TECHknitting. I have just finished reading her post for September 30, 2009 and it is full of many great ideas. But the one I want to specifically point out is the stretchy cast on and cast off.
First, start here with Knitty's article. Then let's look at Cat Bordhi's video of the cast off.
Jeny has also come up with a great technique for a stretchy cast on and here it is.
Isn't it great! I am so easily excited. Next pair of socks I knit, I will have to try the cast on technique.
