When you bind off, remember that since you're knitting in the round, instead of going back and forth, you may need to adjust your technique.
What I mean is, binding off from right to left is natural for most knitters. Binding off from left to right is not done as often. In a traditional straight needle sweater, this isn't an issue. You're starting a new row when you turn at the end of the old one, and binding off is easy. Here, there will be no "end" and turn around point.
That that make any sense?
