craftgrrl | Button Making w/Badge a Minit?

I looked through the memories but didn't really find the answer to my question.

I'm lost, basically. This box full of parts for a Badge a Minit button maker were pretty much left with me to figure out, and it is sans instructions. The buttons are for our College Democrat club event in a few weeks, and I am in charge of button making.. whoopee.

I found some instructions on their website, but what I need is a template.. some blank document with circles the size I need to cut out, so I can design the buttons on the computer and print them off. I think I can figure it out from there, but I really don't know how to go from my idea for a button to the actual print off that is the correct size.

Am I making sense? Anyone have a blank template they use or know where I can find one?

Thanks gals!
