How to hang your extension cables on the wall

I used to store my extension cables in a drawer, which is not very efficient in terms of space-usage. Here is how to make it better:

Screw a large L-bracket to the wall and bend it a little, you'll end up with a hook like this.

Done. Now you can hang the extension cables on the wall.

The only thing you have to do afterwards is figure out what to do with the free drawer.
