The new Knitty came out a few days before I bought this yarn and I really like the Double Heelix Sock. Unfortunately my brain could not handle it while visiting my parents & waiting for the web page to load on my phone (with “E” connection) so I recalled when Grumperina did her Helical socks which used 4 colors knit in one round each. I thought, ‘hey, I can do that!’
