I got past one repeat of the yarn. It took most of a 9.5" foot of a 72 stitch sock:
I felt a little bit bad that I didn't wait until the Doctor Who swap arrived before buying the A&C yarn. In my defense, I never expected my swap partner to be able to find it, let alone get it in a color I picked myself. The good thing is that I can go ahead and use it for socks and for a shawl pattern. I found The Sock Knitter's Shawl and thing it would be big fun to knit with this yarn.
I spotted something on Ravelry that the author calls a mega-pattern. It's an appropriate name. It has 52 Christmas/winter motifs plus hat, pillow, sock, and scarf patterns you can use them to make. The motifs are really nicely done. I think I must have this pattern. It has a cat in a Santa hat that looks just like my Jasmine cat. Here's the Ravelry link to InfiniChristmas.
