Okay, I can figure out how to cast on, and I remember knitting and purling, but casting off doesn't stick in my mind after a year or so has gone by. So here is a helpful link:

It has several varieties of casting off, some of which look very useful even though I will never actually use them.

The basic technique: "Slip or knit the first stitch. *Knit the next stitch. Pass the first stitch over the second. Repeat from *. "
