A string of beach treasures casts a dreamy glow on a patio or porch. Decorate a string of small white lights with clean, dry shells. Tape a 2-foot section of lights to your work surface with bulbs lying flat. Apply a thin layer of epoxy along the hinge edge of a shell, and press into place at the base of a light. Repeat for each bulb. Let dry about five minutes before continuing with the next section.
