Usually I refer to my projects according to the name of the color on the label, like my Red Hots Sock, the Bubblegum Afghan, or the Cherry Cola Afghan.  But this one was assigned an unimaginative color, according to the label:  25.  So the #25 sock it is.

The heel is turned, so now I just have to knit a few rounds in stockinette and then start the ribbing for the cuff.
