Papier D'Arménie

We picked up a pack of these Papier d'Arménie air purifying strips from Labour & Wait. You light one end of the paper, and then let it smoulder away (in a very French manner). The official website is really beautiful, and has some fantastically written French prose too. Apparently, the scent of the strips "is believed to have purifying powers, and be able to eliminate all impure and coarse emotions and thoughts".
