For your grandpa who likes paper folding, I suggest you consider the following gift ideas:
1. Origami Books: If he enjoys paper folding already, he will definitely appreciate books that teach him new techniques and ideas for paper folding.
2. Origami Kit: You could create a custom Origami kit for him, with an instruction book, Origami papers, and even some frame to display his creations.
3. Paper Stock: Gift him a high-quality paper stock that is typically used for origami, so he has the materials he needs to create beautiful paper art pieces.
4. Origami Workshop: A membership to an Origami class or workshop could be a really fun experience for him.
5. Origami Chess Set: If he is also into chess, you could gift him an origami chessboard and chess pieces set, which he will surely love to show off to his friends.
Hope these ideas help you find the perfect gift for your grandpa!
