It's finished. It is the first knee sock that I've had that comes up my leg. Next time I will make it about 2 inches longer as it doesn't quite reach my knee, but I'm still very happy with it. I need to get some 16 inch circular needles.
If I did the math right (knitting math, hmmm) I have the calf increasing to fit my larger calf. I have been increasing at the back almost every round. This should, un-stretched, be about 19" (yes, I have huge calves). This should fit with a little stretching.
This is why I'm trying to learn how to knit socks. I have very large calves so forget about finding any knee socks that actually fit in the store.
On these socks the heel is done by what is called "Short Row Heel". I followed the directions I have after several readings and an internet search for help (YouTube has great videos to help you). Wow, these directions are wicked fussy. There's YO front and back, increases and decreases, and parts missing from the directions. Yikes.
I persevered and was able to get the heel turned. I have to say, though, on the next sock in this pair I will try a technique I found while trying to figure out these instructions. On YouTube it has this tittle :
"Short Row Heel Demo - Lifestyle Toe Up Socks, No wraps!"
It seems much easier and still makes a heel.
