This is a shoebox I decorated a few years ago. I had the idea to stick to it small pieces of paper that would imitate mosaic tesserae.
I cut small colored squares of paper out of magazines. It took me ages! On the other hand, it was very effective to relax after a stressful day. Then I sorted the pieces of paper by color and I glued them to the box cover. I’m happy using this cardboard box with a spiral pattern as storage.
