If you're looking to add a design to a wall, ceiling, or piece of furniture, stencils are a great way to do it yourself. You can purchase a stencil at your local hardware store or online. Stencils come in a variety of sizes and designs, so you can find one that fits your project perfectly. Once you have your stencil, simply trace the design onto your surface with pencil and then paint over it with the color of your choice. When you're finished, peel off the stencil and enjoy your new design!
