Firstly, we recommend alternating folding your collapsible backdrop with the front and backside facing outwards, each time you fold it avoid this from happening. However, if it does happen, don't fret! Grab a friend and grab opposite corners of the backdrop and begin to twist. As you are twisting the backdrop stretch the backdrop slightly. This should 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.
