Aaaah! I see. The flap looks separate and then it is picked up down the edges at either side. The pattern I had confused me. Confusion is now gone. I had not knitted socks since I was at school and I'm in my sixties now. Many, many thanks from England to US. Linda.
It was very good to see the work done and progressing. Much easier to understand the "cup" side of the heel. Thank you. From England to the US. Linda.
