Mmmm, smells good. From Katherine:
Take one orange (or clemantine, or whatever… but full-size oranges smell nicer) and stick whole cloves into it, pointy end through the skin. You can lay these out to make a picture, or abstract lines, or whatever, and it smells heavenly (try setting one on the fireplace mantle or near a hot-air vent).
To make it into a Christmas tree ornament, before sticking in the cloves, tie a ribbon around the orange (top to bottom, then make a cross with the fabric and go back up the sides — like wrapping a box), then make a tight knot at the top of the orange, and a loop above that. Next, add your clove studs.
The orange will actually still be edible on Christmas morning (if that’s your thing…).
