Valentine's Day has always been one of the biggest "crafting seasons" in our household. My daughters especially like making crafts that incorporate pieces of candy to share with their classmates instead of giving out Valentine's Day Cards. We usually do the crafts assembly line fashion, as a family, so we can pump out enough "product" to share with everyone in both classrooms.
As much as the girls love the candy crafts and dad likes "helping out" by eating the leftovers, my personal favorite since I was a little girl has been making animals out of hearts!
(heart angels, etc)
