I went to pick up a trunk one day and the former owner gave me a stash of boards. They were the kind that are used for shelving in many of the Sauder type TV stands. They weren't good for much.....or were they? I thought aha! I could make them into chalkboards. So I cut them into shapes and painted them with black chalk paint. Not bad, free boards that probably would have been trashed if I hadn't taken them and re-purposed them!
This is an old sled that I made into a chalkboard advent sled. I used a picture frame to make the chalkboards. Rusty old bells adorn the wire handle.
