How to make a cool flower vase that would make your flowers look like a masterpiece of PVC boards? You’ll need a drill, some PVC, a piece of Lexan, shelf pins, silicone and some simple instruments. Cut the 3/4″ × 3-1/2″ PVC trim board for the tops, bottoms, and sides of the vases and 8″ × 10″ piece of Lexan into two 5″ × 8″ pieces for the front and back of the small vase. Dry-clamp the front and back Lexan panels against the assembled vases and position the top. Drill 1/4″ holes 3/8″ deep into the top ends of the sides and the bottom face of the tops for the shelf pins, silicone the shelf pins into the holes in the top ends of the vase sides, centering them in the holes; then fill the 1/16″ pilot holes in the tops with silicone.
