I'm casting on for mittens and as I'm going to be doing ribbing I thought I'd try a more flexible cast on method - I usually use the long tail/thumb method but it doesn't seem to be stretchy enough. I'm having a go at the "Alternate Cable Cast On" from the video which shows k1 p1 in preparation for single rib. Would this work just as well for double rib? (if I cast on k2 p2). :? Or... does anyone have a tried and tested method?
