I did a test setup for our swap meet booth, but I needed to get creative for weights on our canopy. I had an idea to try out car suspension springs as weights for the canopy, and it worked great!
I used Bungee cords for canopy weight (Amazon).
I did this for all 4 legs and its holding up very well to the wind here…. Its a lot of weight in all 4 car suspension springs. (I should weight them.)
