Didn't you or chany or dragonmaster dan have a neat mousepad, too?  Wish i could find a pic of those things...
I know i got one of your 
 DoxPhile.com mousepads. I hope i was meant to get it. Maybe you gave one to someone else, not sure. But i still use it in my dorm.
1ST! How much did nullity pay you to plug that? 2ND! They are 2.25inch and my son made them at high school. They got a nice button maker there.  
No payment, free publicity sponsored by 
 DoxPhile.com. But yeah those seem like the size i gave null. Seems pretty good. I've used one where you just put pieces on top of pieces and smash them together to pretty much make a button. It's fun to use, but it would take forever to make mass quantities.
