I like collecting nice wood to use for projects later, so as soon as I saw that shelf, I took it and stored it away for later. The best part about it: I essentially bought the piece of wood for minus 2 francs because we will be able to use the trash disposal sticker for a different piece of trash later.
Today I finally got around to doing something useful with that board. I've long had a nice big set of shelves for all my tools in a compartment in our basement (these compartments measure about 5 x 10 feet and are meant to be used for storage). Today, I attached that piece of wood to one of the shelves and thus created myself a little workbench. I'm really happy with how it turned out and how stable it is - it's nice to not have to work on the floor anymore!
