How about coffee mugs?
Is there a market for those? I've had a few good ideas I'm sure lots of people have.

I love the coffe mug idea. I have been thinking of it for a while. I know I would buy them.

I used to sell my art mugs at craft fairs and they were even bigger sellers than the tshirts.
They should be dishwasher safe though
I think coffee mugs would be a great idea and maybe even placemats to put them on as well.
