"One of my favorite printables is the mystery Valentine's Day message and decoder," Maureen says. "We include a little cute printable envelope template that you can use to carry the fun mystery message. The kids can decode the message with their printable-flag-embellished pencil (we found the pencils at Target for $1!). They can match up the mustache style with the letter to decode the message. I have a feeling my boys' friends will love this!"
