I purchased the 3D image file of the Last Supper from Etsy. I engraved it on a 12" piece of Cherry Plywood. The file had a cut line to cut out around the engraving to make it look like a scroll or curtain. I then glued it to a wooden plaque purchased from Michaels. I stained the plaque with a light Oak stain to let the dark pop from the lighter wood behind it. Finally, I glued the engraved picture to the plaque securing it with wood glue and clamps.
