Abstract
A sheet drape is folded first in one direction into a multilayer strip of material and then in the orthogonal direction into a stack with a first end of the multilayer length located on top of the stack and the second end located within the stack. The drape is unfolded by pulling the first end of the multilayer length in a first direction, to reveal the second end; pulling the second end in the second, opposite, direction (thereby returning to the form of the multilayer strip); and then opening the folds of the multilayer strip.
