Try as we might to prevent it, houses get stinky. Food smells leach into curtains, housemates let off nuclear farts, pets drag in assorted detritus.

And for that, Design Love Fest has a doozy of a tutorial over here. Combine just a few ingredients and you'll be breathing in the loveliest scents in no time.
