How to Build a Headboard and Footboard from Bifold Doors

Mark the base of the crown molding to the width of the headboard. Position the crown upside down on the deck of a miter saw, braced against the fence and deck the same way it would be positioned against a wall and ceiling. Cut the ends of the molding at 45 degrees for outside corners. To create returns for the mitered ends of the crown, cut two more pieces of molding 1 inch wide, with a straight cut on one side and an outside miter on the other.

Put the three pieces together into a three-dimensional top, joining the returns to the ends with wood glue and 4d finishing nails.
