The game side. We've already played a few times. (I let him win a few... but not all... games). ;P I got the 'X' here. For the 'O', I just chained 20, then joined to make a ring. Then 2 dc in each chain. Or, you could probably do the O that's on that alphabet site... He wanted and X and an O like the real game. :P (Instead of the hearts and o's...)
I am working on finishing up a Squiggly-Wiggly potholder I started a looooong time ago, too. It is totally messed up, but I am just going with it.
