Adding a pattern to the back of a bookcase or china cabinet is a great way to give it a shot of personality. Linda figured out a great way to do it with ease AND a fear of commitment.
Instead of painting (or wallpapering, or attaching fabric) directly to the backside of her china cabinet, Linda cut a piece of foam core to the same dimensions and painted her stencil on that.
This way, she can easily remove it when she wants to switch up her color scheme, plus it's way easier to paint a piece of foam core rather than trying to cram a stencil inside a cabinet and paint that way.
Linda has a full tutorial with some helpful stenciling tips on her blog, Burlap and Blue.
