I have a love/hate relationship with laptop bags. I enjoy the look of my over-the-shoulder messenger bag, but it’s not the most comfortable thing in the world if I have to carry it around for long periods. Alternatively, I have a nice backpack that is much more comfortable, but is bulky and doesn’t quite give off that professional look that I want. Well if you want the best of both worlds, you can actually convert your messenger-style bag into one that can be worn on your back.

This simple guide shows you how to take a strap from another bag to make the entire thing sit on your back. This takes very little effort, and if you have a spare bag lying around costs absolutely nothing. When you want the over-the-shoulder look, just move the strap, and you’re all set.
