I just happened across this blog post from Centsational Girl earlier today. I don’t know how she figured this out, but it seems pretty easy. All you need is some non-standard grout and latex paint. I doubt we have any grout laying around, but we definitely have a lot of left-over paint from when we moved into our house. I’ve been wanting to paint something with chalkboard paint for a while and now I know I can make it in any color I choose!
