I can see it now: Tonight, on a very special Trading Spaces, Mindy Paige Davis Page and the gang turn their attention to a block of outdated gingerbread tract houses in Washington, D.C. Decorator Frank Bielec adds rustic charm to a dated “snap” kitchen using minty-green frosting to create his trademark freehand ivy border. Over at the neighbors’, Hildi Santo-Tomas paints the ceiling with bittersweet chocolate to give the HO’s generic great room a cozier feel. Hunky handyman Ty Pennington uses walnut icing and graham crackers to build a kitchen island and to re-purpose an armoire. Can the designers stay within their thousand-dollar budget? Will the frosting harden before time runs out? Perhaps they should simply demolish the outdated gingerbread structures and build anew. Pastry architect Jan Curry will demonstrate how when she presents the “How to Make a Gingerbread House” workshop at 10 a.m. at the Smithsonian Arts and Industries Building’s North Hall, 900 Jefferson Drive SW.
