Connect the elbow fitting and T-joint with an 8-foot piece of PVC. Insert a 1-foot piece of PVC into the opposing ends of the five-way fitting, to create a second set of legs for your backdrop. Place an 8-foot piece of PVC onto the floor, in a horizontal position.
Slide the left end of the PVC pipe into the remaining hole of the five-way fitting. Place a five-way fitting onto the right side of the PVC pipe. Lower an 8-foot piece of PVC into the five-way fitting, in a vertical position.
Place a T-joint atop the piece of vertical PVC. Connect the two T-joints with a piece of 8-foot PVC. Insert a 1-foot piece of PVC into the opposing ends of the five-way fitting, to create a third pair of legs for your backdrop.

Wrap a large sheet of seamless paper around the skeletal structure of your backdrop. Secure the paper in place with numerous pieces of duct tape. Draw landscapes and designs onto the paper to complete your stage backdrop, if only one is needed for your production. If more than one backdrop is needed, paint each one on a separate sheet of seamless paper, and change them as needed during the play.
