Enthusiastic students who come up with ideas design the buttons for our team in their own programs (generally knock-off photoshop tools). We've been using adobe illustrator to resize them. The actual size of the design depends on your button making tools and the size of the buttons you're making; what we do is use a tool like illustrator to get it to best scaled size within the circular constraint, and then put it on a google docs template to print 12 buttons/page.
