I did my swatch, measured it, chose a pattern (I really don't want to have to adjust a pattern to fit my yarn/needles), and... nearly cast on.
For the Knitting Olympics. Whoops!
(rules are that you cast on during the opening ceremonies and finish by the end of the Olympics. Swatching ahead of time is OK; casting on is not.)
I'm going to try to do two at once on two circular needles. I hope it works out well!
