Five Star Gift Ideas

That's a great hobby! Here are a few Father's Day gift ideas that you could consider:

1. Shot glass collection: You could help your grandpa add new shot glasses to his collection. You could find unique shot glasses from different places, like a local brewery, a souvenir shop, or online.

2. Shot glass display case: You could also gift your grandpa a display case where he could showcase his favorite shot glasses. There are many different types of display cases available online, ranging from simple wooden cases to ornate glass shelves.

3. Personalized shot glasses: Another idea is to get your grandpa personalized shot glasses. You could have his name or initials engraved on the glasses or have each glass represent a different place he's visited, such as a shot glass from each state he has been to.

4. Shot glass book: If your grandpa is into history, you could gift him a book about the history of shot glasses. He could learn about the evolution of this unique glassware, which might enhance his enjoyment of his collection.

5. Shot glass cleaning kit: Finally, you could put together a kit that includes everything your grandpa needs to clean and maintain his shot glass collection. This could include cleaning solution, polishing cloths, and a soft-bristled brush.

Or you can get him a star map with an important date you share.
