Success! And failure.

Well, I did the heel flap successfully! Except that now I can't fit it on. I'm persevering, since I often can't get short-row heeled socks on right after doing the heel either - somehow continuing up the leg makes it go on better. I hate ripping back, so much so that I might find someone they'll fit to give these socks to, even though they're only about 33% done. Beh. At least now I get how heel flaps work!
