I was brainstorming an easier way to quickly and easily tension the flow frame cable and a very simple solution came to mind. I considered other options, mini-turnbuckle, cable clamps, etc. but those are bulky or relatively costly.
It adds very little height, but you could use something thinner as long at its fairly rigid. But certainly there is enough clearance from the inner cover to make this popsicle stick trick work for me! Way easier than getting the wire on and off.
Maybe @Faroe could run it past the design team and Flow could integrate this sort of design into future flow frame versions but have it look more elegant.
