Chalkboard

I made a chalkboard for a corner of the kitchen. I am disappointed in how it turned out:( I wanted the surface to be smooth, so started out with a smooth board, primed it, sanded it, then a couple coats of chalk paint (spray on, then used a roller) and the surface is still a little rough. I'm just going to pretend it's supposed to be that way because it's an "antique". But, it's not. Oh, well! It is large (3'x4') and I picked up the frame for $1.00 (!!) at a yard sale. Distressed it because that's the thing to do right now. Or like my son Jake would say, "everybody's doing it!"
