Pretty socks knit top-down in the round with mirrored cables. Work up quickly in worsted weight yarn at 6 st/inch. You could also use a sport/dk if you can get that gauge with them. I use these as slippers! they are quick to knit and comfortable to wear!

January, 2015: KAL in my group, with added instruction for working these on two circulars.
January, 2015: changed the initial cable to add some increases as people were finding them a bit snug there. Added definition for pfb, and changed counts for both sizes.
