When Jake informed me that golfers like to mark their golf balls in some way to differentiate them from other balls on the course, I knew we had a Father's Day gift idea on our hands.
We took a small box of golf balls and a Sharpie, and let Sophie do her magic. Personal favorites include the top left ball "Sophie giving Mama a present in the shape of a heart" and the bottom left "Sophie's face next to Papa's face".
Jake will have no problem finding rogue golf balls on the course now. But he may have issues with people wanting them for their own. They'll have to commission their own kids for that.
