Pretty frustrating, but each time I kept telling myself "hey. it's just a little sock. not much to rip back and reknit....after its timeout." It started having 3 charts; now there's 2. I've also switched up the heels and ribbing. Susi offered a very helpful tip, as well; many thanks!
I think it's there. It's super comfortable and warm. But I guess now it needs a mate.
