Abstract
A collapsible structure has a base panel that includes separate first and second sides, a foldable frame member having a folded and an unfolded orientation, and a fabric material covering portions of the frame member to form the base panel when the frame member is in the unfolded orientation. The structure also includes first and second loops, each loop having a foldable frame member having a folded and an unfolded orientation. The first side of the base panel is coupled to the first loop, and the second side of the base panel is coupled to the second loop.
