Okay, I have gotten past that part. I got the circle started, I made the "toe" area and then have done a few rows of hdc to create the heel... except that's where I'm stuck. I don't know what to do next. (It seems like it should be intuitive but evidently I'm not that smart!)
I've done up to this: [ch.2 hdc in next 14 sts. turn and repeat until foot length is what you want].
It then tells you to put the right sides together and slip stitch shut. BUT I have no idea which "right sides" you're putting together... and then, what do you do next in order to make the tall cuff up the leg????
Thanks for the help everyone... slowly but surely, I'm getting there!
