My son was looking over my shoulder as I was reading February's Scrapbooks Etc magazine and saw their robot valentines. So we made a bunch. They used mini hershey's bars wrapped in some quick digi paper I whipped up. I scored and folded the arms and legs and used some punches I had around for the head and eyes. I bought a pack of "sticko" brand stickers for the hearts. My son (age 5) was able to help prep everything except the cutting of the arms/legs and bodies (he used the punches for the head and eyes) and he glued everything down (excpet the bodies, which I wrapped and stuck down with tape so he didn't get glue on the candy). They turned out great!
I cut cardstock in half and folded it to make the cards, and he wrote "Happy Valentines Day NAME Love Adam" in all (we did 15) of them!
