Measure the perimeter of the ceiling with a tape measure. Use the measurements as a guide when purchasing lattice to go around the entire room.
Cut each piece of lattice into 18-inch by 8-foot long strips with a skill saw. Sand the rough edges.
Frame each piece of lattice with 2-inch wide wall molding. Nail the molding onto the front edges of the lattice with 1/2-inch long finish nails.
Lay the lattice on a flat surface, front side down. Screw 2-inch by 2-inch thick wood blocks along the edges, every 24 inches, with a screw gun.
Thread clear or colored string lights through the openings in the lattice.
Screw 3-inch long screws into the lattice, running the screws through the 2-inch blocks, to affix the lattice to the ceiling along the edge of the walls.
Plug the string lights into an extension cord. Hide the extension cords with adhesive wall cord covers. Paint the covers to match your walls if necessary.
Purchase five 8-feet by 2-foot pieces of lattice. Spray paint the lattice in a single color that complements your decor, or use a different color for each piece.
Screw eye hooks into the corners of all the pieces by hand. Set the lattice aside.
Affix five self-adhesive outlet strips to the ceiling. Stagger the strips to create a zigzag pattern across the ceiling. Center them where you plan to place each piece of lattice.
Connect each outlet strip into thin extension cords run from the ceiling into plug outlets on the walls below. Shoot industrial staples over the cords with a staple gun to hold them in place. Cover the cords with adhesive wall-cord covers, or camouflage them with plants or hide them behind the draperies.
Plug two to three single-bulb vertical lamps with cords, varying in length from 8 to 12-inches, into the outlets.
Screw eye hooks, four for each section of lattice, into the ceiling by applying firm pressure to the hook and twisting it by hand. Hang 6-inch small-link chains from the hooks.
Hang the lattice from the ceiling by threading the bottom links of the chains into the hooks attached to the corners of the lattice pieces.
Pull the lamp cords through random openings in the lattice. Screw in 13-watt bulbs to complete your lighted ceiling decor.
