I love self-striping sock yarn, but I always figure if I’m going to knit socks, they ought to be in fancy complicated patterns which never show up well in those yarns. It doesn’t help that I live in southern California and almost never wear socks -- so I have a growing pile of neglected sock yarn that has been needing some love. I wanted to make some armwarmers with it, but I searched the internet high and low, and basically every armwarmer pattern ever written is for worsted-weight yarn. So I wrote my own! These are knit in a simple rib pattern which gives them stretch, and the decreases are hidden in the purl parts. They’re sized to fit my rather average-sized forearms, which are 10 inches around at their widest point near the elbow. The stretchiness should accommodate a range of arm sizes, but your mileage may vary! (Resizing suggestions included.)
