Instructions
Draw two jagged, random lines on a 2-by-2-inch piece of cardboard paper. The second line must intersect the first. Starting from the left and proceeding clockwise, label the corners with letters.
Cut out the four shapes. Cut the lines only up to the intersection.
Place the shapes next to each other, in their original position. Swap pieces A and C, and then pieces B and D. Tape them together so that they do not slip.
Place the new shape on a sheet of paper. Trace the outline with a pencil, move it over so that some of the edges fit, and then trace it again. Do this several times.
