Instead of priming the tray I used sand paper.
I picked up this chalkboard paint at Menard's for $9! They have one that is actually dye able so you can choose a variety of colors. I choose classic black.
I picked up this plate holder at the same flea marker for $1. It needed some updating I used leftover pink spray paint. It took 2 layers of paint and it was good to go.
I'm quite proud of the turn out! We went to a few stores looking for chalk and have had no luck but Ill stop my an office store soon. The chalk paint took 3 layers for a even look. It drys very fast & was very easy to do.
