Simply wrap each panel around a tube. The photo shows each panel wrapped around stacked cement mold tubes from Lowes. This makes them wider trees. The panels are heavy poster paper, so they can also be taped to a wall and rounded out to look 3-D without a tube. The panels can be cut in half (lengthwise) to create two trees out of one panel. Tape them flat to the wall or to cardboard cut-outs. Tree panels are shipped in mailing tubes so they can be rolled up and stored for future use. This is a prop investment to use again and again.
