I use card stock to make up the calendars I make each year for our family. I enter holidays as well as family birthdays and anniversaries with the number of which birthday and anniversary. At the end of December I include each side of our family (our children’s grandparents) each family is divided up under their parents with their children and grand and great grandson listed. Such as my husband and myself’s parents children their children etc. with all cousins aunts and uncles listed. It makes it easier for the “ in-laws” entering into the family to keep everyone straight. It is so much fun.
