The Four Ps

I’ve been putting the rubber band behind the the hook of the top bracket. Am I supposed to put it in the middle where the groove is (or something) and then pull it to hook the other brackets?

I’m not asking for the formation, just HOW do you attach the rubber bands.

Okay..go to your top bracers and find the hook and then drag it down to bottom and find the hook there, its either infront or behind the origional one.
