Steps:
Plan and measure where you want the lights.
Decide how far from the ceiling you want to put the molding.
3” to the bottom of the molding (lights about 2 ½” from the ceiling) looked best for my room.
Mount the molding. Mitre the corners.
Tap in the finishing nails with the punch so you don’t bang up your molding. Caulk the bottom edge and the corners
Peel the backing off the lights and lay them on the molding.
Add connectors wherever strings join together. Match +’s and -’s.
Run power wire to strips.
Add power every 2 strings, or about every 30’.
Decide where you want your switch. Wire it and mount it.
Enjoy your beautiful, elegant, cheap new lights!
