What a terrific idea for grandparents! Gather your best pictures of the year and every important date for the family to customize a 2013 calendar. That way, each time they will look at a calendar, they will think about you! Several superstores and pharmacies offer this service on their websites. Allow a few weeks for delivery. Expect to pay between 12 and 30 dollars, depending on the format. You can also customize other objects: coffee mugs, mouse pads, t-shirts, etc.
