I just got done creating a wrist warmers pattern generator on the Knitting News Cast website. All you have to do is knit up a gauge swatch using any yarn you like. Then enter your gauge, wrist size, and needle size. The pattern generator then creates a custom wrist warmers pattern. Too cool!
I had a lot of fun knitting up a couple pairs of wrist warmers using the simple K2P2 pattern.
Here is a picture of one of the wrist warmers I knitted using Buckwheat Bridge Angoras Yarn (50% Kid Mohair, 50% wool, Corpus Cristi)
