Making Valentines? Use these adorable, easy flat valentines for classrooms, friends, family or dress them up into more complex cards and paper projects! We've optimized them for mass-production so they're easy to make for a classroom of kids! The largest piece of each valentine can be cut about 12 times (more or less) out of a 12x12 piece of paper. Each valentine has a "blank" shape that you can glue onto the back to stamp or write on (optional), as well as an optional envelope. Get out your festive paper and get cutting!
