That's great! Here are a few gift ideas for your grandpa:
1. Purchase an abstract painting from a local artist or online marketplace, and present it to your grandpa on Father's Day.
2. Give him a painting kit, so he can create his abstract paintings at home.
3. Take him to an art exhibit showcasing abstract paintings, and enjoy the experience together.
4. Create a scrapbook of abstract paintings that you think he'll enjoy. You can even include photos of his own abstract paintings if he has any.
5. Get him a coffee table book on abstract art, so he can flip through it and learn about different artists and styles.
I hope one of these gift ideas resonates with you and your grandpa.
