Well I'm sure at one point or another you have owned or come across a Wooden Calendar holder. I had no use for mine any longer as a Calendar holder, and decided to re-purpose it into a Chalk board. A little paint and about 2 interrupted hours later it was ready to hang. I have two more of these that I found at a garage sale, and will give them new life again.
Much more useful now than it ever was!
