I finally cast on with some of my own handspun yarn. It was my fourth third skein. The yarn is a bit thick for the hat-size circular needles I have. I have it in mind that I should run right out and buy some 12s in that friendly 16″ length.
Knitting with my own handspun yarn has been extremely satisfying. The fiber it came from cost about half what the equivalent yarn would have done, and the yarn would have been about half again as small as the skein I spun. There are thick and thin spots, for sure, as anyone might expect from it being only my fourth skein ever, but since it is plied yarn, it is not experiencing catastrophic failure.
I have very little done so far, just 4 rounds. But it is really nifty to be making something from the yarn itself. 
Oh, and I did not say this before, but handspun yarn is way softer and nicer than most commercial yarns.
