Samm, I had the same problem... I was so frustrated with my *elf* sock that I haven't even started the second one. I left 20% un-short rowed, like the pattern said....I had to tug it to get rid of the pooch as well. But it comes back after a few steps. I would think leaving even more than 20% would help. Too bad there's no real way to tell without doing the whole thing.
