Method: Leave the cap on the bottle. Cut the bottle into two pieces. (You can use the bottom piece to cast a cute cat doorstop, see 82320 to the right.) Fill the candle liners with adhesive putty to slightly above the edge. Attach the candle liners to the inside of the mouth of the bottle. Brush the inside of the bottle with a little oil and then fill with concrete. Let harden. Loosen the mould and remove the adhesive putty. Tape a triangle and apply the turquoise paint. Let dry thoroughly. Tape up a new triangle and paint it orange-red. You can cast the bottles several times as long as you remove the concrete carefully.
