This gorgeous bag offers a way to reuse the tabs from soda cans. The final pattern created by the tabs looks a bit like chain maille or fish scales, but either way, it's ever-so stylish.
The dimensions used here perfectly fit a 13" MacBook, but the proportions can be adjusted for other laptops, or to make other bag sizes. To make sure that the laptop will fit, you'll need to be sure to keep your seams as narrow as possible, or add a little bit to all of the pieces to allow for extra room.
