I've got about 6 inches of my Joan's Socks finished. I just started blindly following the directions for the heel flap and from what I've done so far, they're fairly clear. I'm using the 'just do it' mantra - whatever the pattern says I do, no matter how screwy it sounds.
I tried it on. Its a little snug for me, but since they're for Aileen I think they'll be great.
