F-Stops blow the competition out of the sky.  This eye-catching Bol/Line Laundry Spinner works well as line laundry if you have a very big lifter kite (sled or parafoil). Otherwise it needs to be secured to a substantial ground anchor, as it has a considerable pull, especially when the wind gets up.

The mere size of 14 plus feet will control the skies for attention grabbing, but means that it needs a lot of care.  It will normally require two people to launch it.  It's certainly one of the most eye-catching items you could add to your display.
