I print on anything...metal, like key tags, ceramic mugs, tiles, mousepads, switch covers and electrical face plates, but I also do this printing stuff in my video store, and I have a small copy shop as well (custom printing such as invitations, biz cards etc), and just last Sept, I moved to an upstairs out of the way location and now also have a resale and consignment shop.
I'm in a very small town in rural Ohio and I just "Do it all!"
