To temporarily decorate your household windows to celebrate holidays, seasons or "just because," window clings are the answer. These vinyl clings come in every shape and design imaginable. To apply them to a window, place them against the glass and gently smooth them with your hand. They stay in place because of static. After much use or if the window surface is dirty, window clings lose their holding power, but cleaning them makes them stick once again.
