Chalkboard paint can be used in almost any setting and is a nice suggested add on for clients. Some other ideas for places to use the chalkboard paint is cabinet doors, table tops, toilet seat covers, tv cabinets.
You are not limited to black either. You can custom make your own chalkboard paint in any color you want. If you have done a project using chalkboard paint, post a picture on the Facebook fan page.
Unless noted, most of these photos I found on Pinterest.
