Panels and paint

Good outdoor sturdy display board is expensive. I'm looking at $200 plus. So I decided to try some $2.99 a piece foam core to start. Painted with some Krylon outdoor Hunter Green paint. The next challenge will be  to attach it to the PVC pipe. I ordered some wood grain duct tape from Platypus Designer Duct Tape, not available at Home Depot, Michael's Crafts or Joanne's. I hope to wrap it around the PVC and tape it to the panel on each side. Then I will cover the seam with a thin piece of balsa wood as moulding. We'll see. That's why I'm going cheap for the first try.
