Outdoor patio string lights are another set of lights on string which help to add and enhance the atmosphere of the occasion. For an outdoor party or entertaining, string the lights along fences or the house. Stretch them overhead across the patio. The patio string lights provide light for an evening or nighttime party outside, while adding ambiance to the area. Patio string lights also define different areas of the patio, depending on how they are hung. Rows of lights hung in one area may identify a dance floor or play area for the kids. The food area may be lit with a different style of string lights. Mix and match the strands of lights for overall area lighting.
