In case youc an't recognize them (which, i wouldn't be surprised due to the self-patterning yarn) they're Cookie A's Monkey Socks from the Winter '06 Knitty. The first thing I thought after one pattern repeat was that it looks an awful lot like scales....If it wasn't for stuffing showing through the yarn overs I'd have something to go off of here.
Anyways, I'm using Joanne's ghetto sock brand: Sensations, bamboo & ewe. It's perfectly lovely. One sock nearly done. Baby demanding attention
