is yarn hoarding instinctive preparation for winter?

Someone take away my credit card. I was just innocently browsing KnitPicks and noticed that the sock DPN set I've been eyeing (6 sets of sock-sized DPNs--a must have, since I currently have only 2 sets, and they're always tied up in hibernating, half-finished socks) was on super sale--only $19.99! But it seemed silly not to purchase at least $50 worth of items to get the free shipping. So, yep, I bought even more yarn. Out. of. control.

Finished one sleeve on Josephine. Just need to do sleeve #2, neck trim and seam her up--hopefully all today!
