SECRET: Convert a square or rectangular opening into an archway to call more attention to what lies behind. "An arch is a powerful design element because it has a pronounced center that turns whatever it frames into a focal point," says Davis. So whether it's a fireplace in the family room or the family room itself that you want to highlight, an arch is the ticket. Thanks to new kits, which include an elliptical template for creating a new header out of drywall, curved moldings for the top, and a pair of side jambs, adding an arch is relatively easy and affordable for DIYers.
