It happens that I see the world in different shades of grey. Usually, that upsets me because there are so many things I want to do and I don't want to "wander uncreatively". So the best way to get over it is to do something, anything, using as many colours as possible.
A few days ago I found a little cardboard box and grabbed it. I didn't take much time to decide what I'd do on it because I need to keep my need of colours fresh. So I chose a simple geometrical pattern. I had some fun with the top. You can connect it with any side of the box and create a different combination. This way, you're sure to never get bored of it.
