DIY Stenciled Animal Mugs: Use dishwasher safe PermEnamel paint. This would be fun to do with flower stencils I think and maybe on something other than just glasses like a vase or something.
personalized coffee cups using a sharpie. HOWEVER. I read that this project is VERY tempermental. It was recommended to bake them at 450 degrees instead of 350. I also read that certain mugs won't take. Another alternative is to get ceramic markers instead. I still want to try it, just to see if I can get it to work.
