Ever been in the middle of a DIY project when you suddenly realized you were out of an essential hardware piece? That's what happened to this person as they were working on a repair; they ran out of flat washers in the middle of it. But rather than get upset or leave the house to rush to the store, they decided to get creative and used pennies instead of flat washers.
The result? It's as good as it would've been with the official hardware accessory - but much cheaper! Seems like a win-win to us.
