I'd use the bottom of an oversized tin can, like a 28 oz or larger can of tomatoes.

Sometimes I find large cookie cutters at places like Michaels, AC Moores and Walmart. But, if that doesn't work, what about trying pancake molds.

Call and ask Hill's Kitchen on Capitol Hill. They have tons of cookie cutters.

Hi- I was wondering where I could buy large, girly-shaped cookie cutters that I could use for girls to make pizzas out of. Obviously plenty of small cutters abound, but am not sure if larger, more mini-pizza sized ones exist.

Thanks!
