To avoid making holes in your ceiling, install a hanging wire grid. To make a hanging wire grid, cut three pieces of 1-inch galvanized pipe. Use a hacksaw to cut off three lengths of 1-inch pipe, each about two feet long. Use a hacksaw to cut these pieces to size and then bend them into a circle, so they don't tangle when hanging from a light fixture or other hardware. Cut two more pipes from the same length as the first ones, but cut them longer.
