Here is a great idea from Rachael Ray Magazine. Printable Candy Bar Wrappers. Go to Rachel Ray Magazine and search "sweet-talkers". Or you can experiment on your own computer and printer, any card making program will do, (it really is super easy). Maybe upload a photo of you and your dad with a cute message and wrap it around his favorite candy bar. How about little mini ones with a saying and picture of a graduate sitting around in bowls at a graduation party. Just, use your immagination. Enjoy.
