We had some crafty kids in our class in school - they were lucky and got to make homemade valentines using construction paper, glue and glitter and the really good ones had paper doilies as well and came with candy or gum in the envelope. We saved shoe boxes, cereal boxes or other boxes that would work to be decorated and set on your desk for your classmates to put valentines in. It was always a fun afternoon party at school; great holiday and still one of my favorites.
