I mentioned in my Valentine's post for 2013 that although most small plates with molded borders were probably intended for children, some almost definitely were for adults. I gave Kiss Me Quick to my husband for Valentine's Day last year. It represented my own feelings for him more than a box of chocolates or a card!
