I decided to use the tarp with a different mindset. I am a Skydiving Instructor and needed a ground to air communications system that would allow the students to be at certain points at different altitudes. This allowed me to put these at specific points and have the students be able to visually see the tarps after opening. So far it has been a success and the tarps hold up well.
