This is my Mens Very Easy No Heel Rainbow Socks Circular knitting pattern.This sock pattern is very easy because there is no need to make the heels (usually the most difficult part) and the yarn is self striping. The knitting pattern provides full written instructions covering 3 teen and mens sizes: S (us shoe 6-8.5), M (us shoe 8.5-11.5) and L (us shoe 11.5-13) and there are numerous step by step photos throughout. They are worked in the round on 5 x2mm short double pointed needles in any self striping 4ply sock yarn. I used West Yorkshire Spinners Signature 4ply sock yarn in RUM PARADISE.
