Need create a backdrop for your wedding reception? An easy and affordable way to achieve this look is to use PVC piping to create your backdrop. Below you can see the basic concept for creating a large scale version of a PVC backdrop.
The main section above is 8′ high and 40′ long, each section is 8′ x 8′. The cross pieces that hold it up are 2′ on either side (4′ total).
They are using a 5 way piece for the middle sections…
Before you completely assemble you will want to thread the top pipe through your curtains or use curtain clips to hang.
If you are not using white curtains or sheers (which will blend in with the white polls, you can use binder clips on the back side to join the curtain seams together to cover the white poles in the middle.
I would recommend that you print out an example and take it to your local hardware store, like Home Depot, to get an expert to help you with your final vision. Good luck!
