Some dads seem to collect junk. If your dad has a lot of junk laying around it might be a great idea to decorate a storage container for him. Storage containers can be easily made from any jar in the fridge. A cup sized jar (or a real cup for that matter) is the perfect size for holding pens and other stuff that might me cluttering up dad’s desk. Decorate the pen holder with things that remind you of your dad. You can print pictures off the internet or use his favorite cartoons. Does your dad have a favorite saying and a favorite sports-star? If so, it might be funny to get a picture of that sports star and make a word bubble where he echoes your dad’s favorite saying.
The key is to make the gift as personal as possible. Make it so that there is no question that whatever gift you made belongs to your dad and nobody else.
