DIY: Make an inventive Dry Erase board from old picture/poster frame
Here are a couple examples of how to make your own dry eraser message board using and old picture or poster frame and any sort of light colored backing. I especially like this one with its use of muslin as a background. I would guess you could substitute any sort of fabric or paper background, as long as it contrasted with the color of dry-erase marker you planned to use.
Here is another example using paint chips as the background arranged in the form of a re-usable calendar. Very cool!
