1. Choose the art you want to use, making photocopies if you'd like to preserve the originals. Cut out the images and arrange them into a collage that fits inside the wood tray.
2. Coat the bottom of the tray with Mod Podge and position the images on top. If there are overlapping areas, apply Mod Podge between the layers and let dry, then continue working.
3. Add a final layer of Mod Podge to seal the tray.
Tip: Use Outdoor Mod Podge for a glossy, waterproof topcoat.
