Fantastic - you won't know yourself! I'd chuck some heavy bricks or blocks on as well, make sure it's not going anywhere. Then you have to say out aloud: 'it's not going anywhere' as a spell to keep it from flying away in the wind. Only then is it truly ready.
I have trauma, as a youngster I witnessed several times how the wind tore the nylon. Watching my parents how cold-blooded they were. I realized that they did everything they could, our only thing is to move on after such a misfortune.
I don't' know whether to laugh at this or not. But the strategy of moving on is a good one.
