I got a free sample of the 3' x 2' Super Sticky Dry Erase Surface without really knowing what I would do with it. I am not in a classroom at this point but do have an office with wallpaper. Since I could not stick the surface directly onto the wall, I have applies a cut section to the cardboard backing of a picture frame, after taking out the glass. Now I have a framed note board to replace the notes I stuck to the bottom of my computer monitor. My fan keeps blowing those off, so this looks like a great solution.
