Worked the foot through round 75, then started the toe decreases. Got to the last couple of rounds and realized I had about two feet of yarn left. Gah!
Okay, maybe I can squeeze a round or two off the foot and get enough to finish. So I try it on - and it sticks out past the end of my toes by a half-dozen rounds. Whew! So I frogged the toe shaping and took six rounds off the foot, back to round 69. I'll start the toe again from here tomorrow; right now I'm just too sleepy to try it. It's way past my bedtime.
