Sock Patterns--Swatching and Searching

I'm experimenting with some fine-gauge machine-knitting wool. Holding two strands at once, it gives a gauge similar to fingering weight yarn. For fingering weight wool, I always turn to my knitting inheritance, in this case, the 1947 Columbia Knitting Manual (a bargain at 75 cents!). The sock pattern below works for my 10 stitches/inch gauge on 000 needles. I'm knitting the top ribbing right now, and I hope inspiration will strike for an interesting twist-stitch pattern to spice up the rather plain ribs on the printed pattern.
