If you need to replace your foam-backed insert, please purchase it here! Choose the appropriate size for your Li'l Davinci frame. This is the piece that goes under the corners of the inner tray and insures that the artwork is displayed properly and held in place securely. Just put the artwork on top of this piece, depress it a bit to allow you to tuck the corners of the artwork under the frame corners, and let go. The artwork will spring forward and be held securely. Add new artwork on top of those already in the frame, and repeat the process.
