Basic white curtains are affordable and widely available. Give them a style boost with a quick stencil treatment such as this seaside-style coral design. Lay the curtain on a large work surface or floor. Place cardboard or scrap paper underneath to catch any paint that might bleed through. Use a foam stencil roller to transfer designs all over the fabric.

DIY Tip: To make the curtains washable, use fabrics paint for this project, and heat-set according to the manufacturer's instructions.
