My dad has 5 grandkids, so I bought him this fun card from All Around Whimsy. It has the 5 things we love about grandpa. Each grandkid filled out a numbered card that fits nicely in the pocket.
I almost lost my dad 2 1/2 years ago. I cherish every day we have with him. Regardless of what you give, or how you remember your dad, just be sure to cherish the time you have together.
Happy Father's Day.
