So chalk-boarding a mirror or glass couldn't be easier.
Clean the surface and be sure to tape up the sides and spray away.
The spray paint I used was: Krylon, 12 OZ, Black Chalkboard Spray Paint.
We used the three chalkboards to do our menu, welcome sign, and a sign for down at the ceremony.
The teacher/bridesmaid was given the special privilege of writing the signs!
