I have a small kitchen and a lot of reusable bags. I also hoard paper bags, and the combination of all of these factors results in a real cool pile that I keep shoved under the sink. Luckily, there is a cheap solution to this problem: file boxes. Photo by Kristin Bauer.
The idea comes from the blog Everyday Organising and is almost stupidly simple to execute. Just grab a couple of filing boxes, such as these ones from the Container Store (size large), and drill them to a cabinet door or inside a cupboard. File your bags in the boxes and bask in the glow of feeling very adult and organised.
