If you have been struggling to come up with an idea for Father's Day, I have a quick and easy solution for you. These printable gift cards are inexpensive as well. Just print the file out onto card-stock and cut them out. Use all of them or some of them. You can have each child write their name on the card so Dad knows who to plan the activity with. Print out multiples if you need additional copies of the cards.
