Yarn Chicken

Who wins? Me or the quickly decreasing bit of yarn? Photo on 3-31-15 at 9.06 PM

Two rows to go. Two rows, and a bind off, and this tiny, tiny bit of yarn.

Did I figure it wrong? Will it hold out? Does my stash hold something to tide me over, should the ball betray me? Or must I rip 40 rows of knitting to make sure I have enough?

Knit, knit, knit, yarn over. Why must you take so much extra yarn?

Purl, purl.

Cast off. Enough, by the skin of my teeth.
