Carrying an endlessly versatile binder clip around in your pocket makes you see the world differently. Bring it to the grocery store, for example, and that grocery list that normally has nowhere to rest can attach to your cart as a kind of heads-up display.This came about because I'd started carrying around a mid-sized paper clip in the inner pocket of my winter coat late last year. I like having useful stuff on-hand, like hand sanitizer or a mini Leatherman, and added the binder clip as an afterthought one day. Then, one day, while trying to either make my printed shopping list easy to yank out of my pocket, or trying to anchor it inside the top basket without falling out of the two gaps they create for children's legs, I felt the binder clip in my pocket and thought, what the hey.
If you're printing your grocery list from an app or website. — ZipList — you'll want to print with a larger text size than you'd normally use, as your list will be a good 3m away. And I'd bring a marker instead of a pen to check off items, so you don't have to reach down and support the paper while you write. Those caveats aside, the binder-clipped grocery list is one of the many reasons I continue to keep a clip in any jacket I wear.
