1. Combine crayons and candle wax in cheap chocolate molds to make custom birthday cake candles.
2. Pick up a few basic ingredients, then make as many bath bombs as you want on the cheap.
3. Take off the bag in your old college laundry hamper, then paint it and top with a pretty piece of wood to make an instant side table.
You'll want to make sure the frame is sturdy enough to support a piece of wood like this, and that the top is secure enough to the frame so it doesn't fall apart — as in, read the tutorial, don't just try to balance a piece of wood on top of an unstable frame. If you don't have a spare piece of wood around, you could use a cutting board that fits the top of the frame (and use it in the kitchen, too).
