Tennis & Golf Target Rings - Set Up in Seconds / 6-ft Rings

Tried these for the first time, no wind on the court. Could not get the loop above the net to stay up. Tried tying it lower so there were only two (2) feet above the net and that did not work. Tried making an oval and that did not work. I did not find a way to have a 4' loop over the net as the image shows.Next time I will try using both at once, one on each side of the net and Velcro these together above the next to make a sturdier suspended frame.
