This comes under the heading of geeky, science knitting. It is a double helix scarf. The pattern was developed by June Oshiro and can be found here. I made one before – this is my second one – I may finish it some day. The first one I made from worsted weight wool – it turned out great. I wanted to try one with a little more definition, so I started this one from 2 strands of fingering weight wool on size 3 needles.
It will need to be blocked, but is fun to knit.
