Made a small modification to the nets to better accommodate the pucks.
One came loose last night so I wanted to come up with a better way to secure them. This is what I came up with.
I cut the string that holds the tag ends of the netting together which forms the opening. Then I weaved a short bungee in the loops and zip tied them to the lower ring. I cut the end off so they wouldn't rust and get hung up, then burned the tips to clean them up.
The bungees cost $2.94 from home depot.
Took about 2 minutes for each hoop.
