Pro tip: my neighbor's "measure zero times" joke made me stop trusting my eyeballs
He swung by while I was mounting a shelf in my garage and said, "you own a tape measure, why are you guessing?" I had already drilled 4 holes 2 inches off level, so honestly he had a point. Now I check twice with a pencil line first, but has anyone found a faster way to keep shelves straight without hauling out the level?
