My Dad's Sock

I was asked what pattern I used to make a sock for my father who is diabetic. I combined two patterns basically. I used information and numbers from New Pathways for Sock Knitters by Cat Bordhi and the quidich sock from Charmed Knits by Alison Hansel. I used the quidich sock for the ribbed pattern but I added additional ribs in the back to fit his calf muscle. The next sock I make him I plan to use fixation by Cascade Yarns to offer just a little bit more stretch.
