My daughter absolutely LoVeS this. I just used a pre-cut 2'x4' piece of plywood, sanded it down, and covered it with chalkboard paint. I like the brush-on kind instead of the spray better. It seems to give it a smoother, softer surface to write on. The frame is made out of our left-over 1x6 cedar fence slats, which you can purchase very inexpensively at the lumber store. The frame, however, is anything but professional...but it worked! I used wood glue and a staple gun. I cut to size, then stapled both front and back of the wood to hold together! Then painted, and used wood fence screws to hold it securely on the fence. And that's it! A fun and inexpensive way to let your children show-off their CuTe artistic abilities!!
