I was knitting away on my Yarrow socks, when this happened:
I was doing a purl 2 together, and the stress was too great for my Ebony Lantern Moon Sox Stick.
(sorry 'bout the flash photos)
Fortunately I had 5 needles, and only need 4 to knit the sock. Even so, I'm afraid if I can break one so easily, I can probably do it again. . .
