Picture this. You’ve called together a party with all your friends and family. You and your girlfriend are standing at the head of the table, ready to give a toast. But all the glasses are covered in napkins! What is this? Then, you tell all your guests to whip the napkins off. They do, and discover – thanks to giant letters and pictures on their koozies - that you and your girlfriend are engaged. How better to announce such a joyous occasion than by taking everybody by surprise at once? Just make sure to have a camera on hand to catch their shocked faces as they read their bright, lovely koozies.
