We cut a piece of hardboard the size we wanted the chalkboard. Ours is about 4ft x 8ft. We then painted the hardboard with chalkboard paint (several coats, with sanding in between). Next, we cut 1x3 boards to build a frame and then cut grooves into the inside of the 1x3 boards to slide the hardboard into. At this point I chose to "rough" up my frame by beating it with chains, nails, etc. to give it the impression of being old and worn. Once it was rough I used a basic wood stain to darken it, bringing out the rough parts. I lightly sanded the edges to add to the "worn" look. Next we slid the painted hardboard into the grooves and then nailed the frame together. We also added a few boards to the backside to stabilize it.
With the advent of chalkboard paint, it is so easy to create a huge board these days. There's no reason to spend a lot of money on a heavy chalkboard. Whether you use Ashley's method or just paint right on the wall and put molding around it- this is definitely a fun project.
Thanks so much for the how to Ashley! Head over to Ashley's blog for more great ideas, inspiration, and photos.
