I finished off that messy mug...
I have painted mugs before...
Pebeo Porcelaine 150, but once I saw it, I knew I had to try it! You can buy it online at Dick Blick, and they usually have it at Michaels if you have one of those shops in your town.
It is really easy to work with, just paint it onto ceramic or glass or metal, let it dry for 24 hours, then bake it for 35 minutes to make it permanent.
There are a lot of colors and you can mix the colors, but I have had a lot of fun with just three colors (coral red, sapphire blue, abyss black) and minimal mixing. Three little pots have painted more than 15 mugs and there's still plenty of paint left!
My craft night mugs have been in heavy rotation for 18 months and the paint job is holding up remarkably well. Only one shows some chipping. Some of my favorites from the first round are mugs where I took an existing patterned mug and added color and print to it.
I also painted up a little sugar bowl and its lid. I was thinking blood cells, can you tell?
