Half of my garage is a "man cave" ( I hate that phrase), I would like to hang some team flags in the area but the walls are constructed of concrete block. When I "hang team flags", I don't mean with a pole. I want them to be on the wall like a poster would be. I've used double side tape (the heavy duty kind) and those hooks with the adhesive behind them. Nothing is working. They continue to fall at the corners.I would greatly appreciate any help / tips. via /r/DIY http://bit.ly/2Z6Jmls
