I finally went looking for my yarn ball pattern (thanks to a prod from Devon
I'm such a slacker, I'm sorry...)
Anyway, Ack! I can't find it in my notebook! I know I wrote it down...
Ok, here's what I remember. It was very simple, so if this isn't exactly what I did, it was close
You can make a larger ball by doing more increase and decrease rows.

Bind off. Thread yarn through bind off stitches and pull this aperature tight.
Fill ball from cast on aperature and then stitch that tight. I found that almost anything I filled the ball with would work it's way out through the stitches, so I found two solutions to this:
1. Stuff the toe of a stocking through the hole, then fill the stocking with the filling material. Tie it off and tuck it into the hole. Or,
2. Wet the wool, then throw it in the dryer with a wet load of laundry to felt it a little.
