tiptop - I'm just like you. I just took inventory of my cookie cutters. I own 487 cookies, plus I have two orders being shipped - delivery expected today. I'm a foosecookiecutter addict and have bought a ton from them. Great pricing. Plus there is a shop about 20 minutes from my house that gets them from there so if I need just a few I drive over there. I own cutters in all mediums. I have copper, tin, plastic. I've had some forever. I have some that were my grandmothers. I have also purchased the copper cookie cutter making kit. I love copper cookie cutters, but they are SOOOOO expensive. I've made quite a few. The baby onsie, a champagne/wine bottle, baby block, elmo, pirate, and a couple of others. Made all those for only 20 bucks. That's a deal for copper cutters.
I don't especially like the plastic ones. I have some that are a thinner plastic, and others that are a bit thicker. The thinner plastic are Wilton and Hallmark. But when you're looking for a particular shape and size, the medium is not an issue, you buy what you can find. The only 'closed' plastic I own are a set of Wilton Halloween, that I love, and a Cinderella and Prince that were too gorgeous not to buy. Have never used Cind and Prince, but they are so pretty.
