So I decided to make my own! Pretty simple, here are the steps. First, get a lucite tray (or a plastic 3D picture frame; you can find them at Michael's and flip them over for the same effect), decoupage, printed paper and a sponge brush. Make sure you clean the tray so there isn't dust or anything that would make the surface uneven.
Put a thin layer of decoupage on the surface, make sure to get the corners and sides. Wipe up any excess that may have made its way up the sides with a wet cloth.
