Upholstery for the lazy girl! When decorating, always keep in mind that no-one's going to see the bottom/back/inside. This is only one small step up from wrapping a loose piece of cloth over a cushion, but it does keep the cover tidy and in place. So: lay that piece of grey denim you're never going to make a skirt from, face up on the floor. Put the cushion more or less in the middle.
I don't think we're coordinated enough to match our throw pillows to our art (well, we did actually in the old apartment, but keeping our spaces uncluttered enough to notice it is another matter...) but this is pretty cool.
