An iPhone holder for my ballet classes. No, I don't dance (silly people!), I provide music to which the ballet classes dance. Several years ago, they repainted the dance studios at the university and never re-installed the clocks on the walls. So the dance professors (since they can't wear their watches and demonstrate/dance at the same time) scurry over to their bag/purse to check their phone for the time. Since then, I made these iPhone holders to prop my phone up so they could see my "bigger clock" app (which you can actually see from across the room). I made one of these for my iPhone 5, then another larger one when I upgraded to an iPhone 7.
