"Fashion your own graphic headboard with playful and chic stencils. To duplicate this look, cut a curvy headboard from medium density fiberboard (MDF) and paint a base coat. When it's dry, use a stencil roller to apply a trendy damask design in a cool contrasting color. Continue the theme by stenciling your design on accent pillows, too." Better Homes and Gardens.
