fast growing socks

Elfine's socks grow very fast. Perhaps it's the Addis, perhaps it's the magic loop, perhaps it's the small number of stitches. Whatever it is, after an evening of knitting (and listening to A Doll's House so it counts as work too), I've got nearly to the heel. Perhaps it's just that the previous socks I was working on were Jaywalkers, which have 92 stitches divided over 4 needles and Elfines have 65 divided over two. I like the lace pattern and it's really stretchy; it fits me and my feet are an inch bigger round than my sockpal's. That makes me slightly worried that they're too big. Hmm. I need to find a smaller footed person to try them on I think.
