I have been wanting to do a chalkboard paint project for a while, and I have also had a good-sized wooden sign that has not had a home since we moved to our new house. Finally, the pieces came together and this project happened. I didn't take a great before picture, but I was able to find a photo that gives you the idea:
I sanded down the part of the wood that had the writing, removed the thin wire hanger, and drilled bigger holes. Then, I painted about three coats of apple green over the top of the black and sanded the edges a little bit. Next, I taped off the area I wanted to be the chalkboard and painted about three coats of chalkboard paint. After the paint was dry, I seasoned the chalkboard paint, threaded on the ribbon hanger, and wrote a festive message!
I am very pleased with the result! I love that I just erase the writing and have a year-round message board.
