I believe in thrift stores. There is already a enormous amount of things in the world, so why buy something newly produced, while there are already so many treasures lying around? I like to re-appreciate those things, already ready to use, and use them again.
One of these treasures was a pile of old post stamps. Somebody collected those, kept them safe, might loved them. Instead of leaving them to vanish, I wanted to put them in the spotlights again. I lasercutter frames, and put those around the stamps. It gave them a certain status, a certain value.
