Not ravelry

While everyone else (it seems) is discussing their projects on Ravelry, I remain loyal to LJ. I have three works in progress as usual but one of the three keeps changing. I've just made one sock of a pair of bedsocks, using oddments of Paton's Fairytale. I have a new plan for socks, to be carried out on the next one I knit. I find that when I make the heel flap, knitting backwards & forwards instead of round and round, the tension is looser. So I'm going to try using a smaller needle just for that section. Anyone else do this already? I've never seen it suggested anywhere. Socks always look better on feet than in photos.
