(though that may not work well for stacking, and I >don't know how you'd get the sides of the pyramid to fit into the base) Have a large square to support the four risers, and a slightly smaller square to provide a stacking rest. The view from underneath would be: +------+ |\ /| | +--+ | | | | | | +--+ | |/ \| +------+ You'd need a seam up one of the risers and along all the base-legs, but it ought to be possible to do this with flat cloth otherwise. On the bottom, the fabric runs to the edge of the inner square, so that the pyramids still look good when tipped over. Roger
