I’m yet another knitter who is trying socks for the first time. On my first sock, the 2x2 ribbed cuff is now long enough to divide for the heel, but I didn’t place a marker at the beginning of the round when I started. So I can’t really tell which needle to stop at so I can divide for the heel. Is there a way (besides trying to count the rows) of telling where the beginning of the round is based on the position of my tail yarn? I cast on using the long-tail method, and then worked that tail into the first round for a few stitches. Thanks!
