What do you do, when you need a small shelf, the next Ikea store is miles away and you don’t have a car to get there?
You build your own, out of the many cardboard boxes that you get when you order online.

Cardboard shelf
The shelf has 2 levels and I combined 2 card boxes from the same shop.
The result is a pretty stable little shelf that we use for our telco equipment. It does not look like an Ikea shelf of course but it’s free and much better for the environment 🙂
