Every year, hundreds of volunteers from across the nation decorate the White House for Christmas in just 72 hours. HGTV documents the process in the annual White House Christmas special — which is hosted by one or two hand-picked HGTV hosts who ensure the First Lady's chosen theme comes to life. Featured designers from years past include Jonathan Scott, Drew Scott, Genevieve Gorder, Zooey Deschanel, Alison Victoria and Egypt Sherrod.
