Upgrade your holiday table with these shimmery trivets.
Coat art board with thinned yellow paint. Let dry. Using a craft knife, cut a piece of copper flashing measuring 1/4 inch larger than the art board on each side. Attach the piece of copper flashing with spray adhesive, and press firmly to adhere. Slit the corners of the flashing where it hangs over the wood base. Tuck one end over the other to create a clean corner fold. Press firmly, and smooth all around the trivet.
