So here it is:
My Dollar Tree baking sheet painted with chalkboard paint, and some magnets. The whole thing set me back $2.47 ($1 each for the magnets and baking sheet, and $.47 for the chalk).
A couple pointers if you do this. 1) When the paint can says, “Allow 24 hours to dry,” it means 24 hours, not 23 hours. If you try to remove the tape around the edges after 23 hours, you will end up with a raggedy edge to your paint circle where the tape took some of the paint off. Hypothetically.
2) When the paint can says, “Allow 24 hours to dry,” it means you should not test out the chalkboard surface with chalk until 24 hours have passed, no matter how dry the paint looks. You may end up with a really cool-looking silver sheen to your chalk marks… until you realize the chalk is actually just chipping off the paint, and the silver is the pan showing through. And then you may need to paint on another coat and wait another 24 hours. Hypothetically.
I’m pretty pleased with how it turned out, all in all!
