Well, every father is different, but I usually make mine his favorite (oatmeal candy) Also things like hair clippers/beard trimmers make great gifts! Mine's favorite gifts are when I cook for him. I've made him peppermint bark before. Usually I make it every year. What is your dad's favorite? Is he big on sweets? If so, he might love something like that! If not, you could get him a funny t-shirt if he's into that sort of thing. They make pefect gifts! I get my partner and dad funny tees from sites that have cheap ones like road kill tees. They always love those crazy shirts!
