Pythagoras’ socks are worked from the cuff down with a heel gusset and a short row heel. Special, cleverly placed increases following the colorwork pattern are worked in the heel gusset. They disappear in the all over patterning and are ’almost’ invisible.
The basic sock pattern is written out; the colorwork stitch pattern is charted only.
