The frame has been warped out of shape and will not stand flat. How do I fix this?

Firstly, we recommend alternating folding your collapsible backdrop with the front and backside facing outwards, each time you fold it to help avoid this from happening.

However, if your metal frame has warped out of shape, grab a friend and take opposite corners of the backdrop and begin to twist. As you are twisting the backdrop stretch the backdrop slightly. This should help return the backdrop to its original frame.

You can also try just stretching opposite sides of the backdrop until it is released into its original frame.
