Pillows- Fastest way to make your room look cozy and comfortable, and super easy! I'm sorry it's not in color, but this article has some great pillow hints.

Corner Shelf for Binders- Blow this template up at large as you would like your shelf base/top to be (Kinkos can help you with this). Trace the template onto two pieces of wood, cut out with a jigsaw. Simply nail boards for the sides, paint and decorate!
