I need help from the knitting community. Caroline has written in the comments that if the heel turns the sock by 90 degrees, then it is a heel. Look at this picture. Does it look like I have turned the sock by 90 degrees? In my opinion, I have. But I need reassurance. It's a long time since I used a protactor and haven't got one in the house. Please leave a comment because I can't knit further until I know.
