Did the same thing in our new kids room, wasn't fun though on something that large, very messy, wouldn't cure right, have to put on several coats. A smaller thing like what you mention would be great though. I even think you could pick up a small whiteboard and use that spray (3 coats or so) on it. Rustoleum makes a spray.
I have found the surfice under the spray makes a big difference, I first did it on the glass of the picture frame, and it did not write very well, so going with a wood back made it a little softer, chaulk writes much better. Lots of light coats vs fewer heavy coats is also a good trick. My board in the shop is like 4x3 feet so decent size.
