You want to minimize the number of panels whenever possible. Introduce a new panel only where you need a doorway, have an obstruction, or are trying to create a certain swagging configuration. Velcro™ attachment panels can be as wide as you like. Also, mosquito netting curtains using tracking attachment can get too wide and difficult to pull around a track. Try to keep tracking attachment curtain panels less than 30 feet wide (8 meters).
