Starting with an irregularly carved cutting board, cut a furniture wrap featuring your own artwork to size and afix to the wooden background. You can also glue a poster to the surface. Apply Easy Cast two-step process epoxy over the entire surface and let dry for a day. If you get out all the bubbles (may require a blow torch), you end up with a high gloss surface. The shown example was sanded down for a smooth satin finish. The example in this image was placed onto a wooden barstool purchased at Target for only fifteen Dollars.
