I started my project by removing the wall paper border "picture" stuck inside the cabinet frame. Actually there were two layers of borders. I had changed the original picket fence and hat scene, to the watering can trowel border, and repainted the door frame to match my outside trim.
My cabinet door is 22 1/2" x 14 3/4". I laid an enamelware tray and a clipboard that I had recently painted black with chalkboard paint out on the door to size up my idea. Hmmm, this might work.
I painted the cabinet door with Annie Sloan Chalk Paint "Old White".
And, as luck would have it, two yardsticks would frame out the cabinet door with none to spare. I found that I had to drill starter holes for the nails or it was very difficult to pound them in straight. The yardsticks were added just for more interest.
That's my cabinet door message center hanging on the kitchen door!
