Burnish your copper pipes by scrubbing them with steel wool.
Cut the pipes into thirty 7-1/2-inch pieces. Be sure to tighten the cutter as it slices, and make precise cuts to make sure the final shape is symmetrical.
Lay out a triangular pattern to form the middle section of the pendant. Twenty cut copper pieces will make nine full triangles and one incomplete open triangle.
Thread long wire through each triangle, tightening as you go. When you get through the last pipe, splice the wire with duct tape, and hide it inside the pipes.
Wrap the middle section to form a drum shape. Then thread wire through to connect the first triangle and the open triangle.
Lay out five copper pieces in a star shape to build the bottom of the fixture. Attach them to the central form one piece at a time, pulling tight as you go. Repeat to form the top of the pendant.
Coil wire around all points for extra reinforcement.
To complete the fixture, insert pendant cording and close the point. Coil wire around the point to secure. Clip the extra wire and hang.
