Glue the cups together (as shown in diagram), using the clothespins to hold the parts together until they are dry. A sphere will evolve after you have glued together about 250 cups. With a plain hanging bulb in the center you have a simple but nice idea in lighting.
Hang onto your old mattresses, too. Especially if you need a new sofa or chair. It doesn’t matter what size the mattress is; however, if you want a sofa, use a double-size mattress or larger. Choose a fabric that you would like to have this sofa covered with and make a bag that fits the mattress. It would be a good idea to sew a zipper in one end to facilitate removal for washing.
Make two canvas panels, as illustrated. These must be as wide as your mattress is thick. Make two grommets on the one end and then sew the panels to the end of the bag that covers the mattress. Fold this end over to the middle of the mattress (this is the seat). Bring the other end of the mattress up at right angles to the seat, then fold it in half. To fasten this you’ll need to make a canvas sling that is as long as the mattress is wide and that corresponds in width to the panels you have made. Place two grommets on either end. Put a heavy-duty spiral keyring in each of the eight grommets. You’ll need four lengths of nylon cord or rope. With these attach the sling to the panels on both sides.
