The weather's cooler, and I've picked up the wool and sticks again. I decided to try the Hiking Boot Socks in "Knitting With Balls". I've never done socks before, and thought this would be a good choice with the larger yarn and larger needles. I completed the heel flap, but can't get the heel turn. Any suggestions? I've knitted it about 6 or 7 times (really) and consulted some other books for hints, but nothing seems to make sense.
