Valentine's Day card exchanges are a rite of passage in preschool and elementary school. Remember the days when we made our own (well, you did if mom couldn't or wouldn't buy you any!) I remember Hallmark made an uber-expensive set of valentines in which you folded heart-shaped tabs over to enclose the message. How about making your own like that with free printable valentines? Use for homeschool groups, scout troops and religious education card exchanges, too. Make DIY valentines cheap. Your clever homemade valentines will be unique and completely different than everyone else's! Free Printable DIY Valentine's Day Card Crafts for Children
