Yes, that little white strip of yarn is a lifeline, and I shouted, "throw out the lifeline" more than once. Frogging is just too cute a word to describe it.
I have read countless online descriptions of how to do short rows with wraps. What seemed to be the hard part for me was exactly how to pick up the wraps. Then I read one that said to always pick up the wraps from the right side of the garment so as to hide the pickup. That really helped, but I still was not sure if I was picking them up from the correct angle.
After one heel was done, I realized there is the little (or big) problem of the hole at the apex of the short rows! Which little stitch(s) do you pick up and knit to alleviate this? Most of the tutorials don't include this and if they do, the description of the hole-fixing stitch does not seem to pierce my brain.
In the end, I did what I felt was a working solution for the hole as I kept telling myself they are only socks, for heaven's sake! If I do this on the toe as well, proficiency may come to me. Or not.
On a brighter note, my Rockin' Sock Club kit came Friday, and it's like cool, man! A real summer love-in!
