Authors note: Reinforce your hinges, or do the hinge mounting internally (L bracket) and externally and just deal with the bump - I had to break this one down due to shoddy assembly work catching up to me. I will rebuild this in the future and show how to get it right.

I have already assembled this one, but assembly is simple.

Place a few support brackets on the lower piece. Add screws as your brackets permit.

Hold the top piece up and add screws to the top side.

Once assembled, you are ready to use the backdrop.
