Three at once

I have three socks on the needles at the moment. The first sock is my March/April pair. I'm using Noro sock yarn and the pattern is Southwest Diamonds. The second sock is for Sam. I'm using leftover yarn from Aric's Christmas socks, and a plain pattern of one inch of ribbing, followed by stockinette stitch for the rest of the sock. The third sock is for Joan, and is the same pattern as that used for Sam's socks, only on two circulars rather than double-pointed needles.
