The Long View
Hang strings of lights from the ceiling about a foot apart along a blank wall, using extension cords to plug each into an outlet. Hang semisheer fabric in front (not touching the lights) to create a light wall.
Wrap lights back and forth to form a tight bundle and place in a metal cup near an outlet.
Run lights around the bases and up the center of plants and trees, inside or out.
Tape lights under a glass table and cover with sheer fabric to diffuse the light.
