Start with the two 2-x-4-foot ceiling panels and 24-inch-square tile. Ceiling tiles and panels are available in a variety of metal finishes and can be painted to suit your color scheme. Cut away four tiles (two on each panel) to accommodate the 24-inch-square tile.
To cut the panels, use tin snips or a band saw. Be very careful when cutting the metal; ceiling tiles are thin and have sharp edges when cut. When using a power tool to cut the metal, protect your eyes -- there may be small particles of metal flying into the air.
