One idea that may be perfect for your grandpa's love of origami is a set of high-quality origami paper and a book of patterns. This will give him the opportunity to create unique and intricate origami designs to display around his home or give as gifts. Another option is to find a local origami workshop or class that he can attend. This will allow him to expand his skill-set and meet others who also enjoy the art of origami. Additionally, you could consider getting him a unique piece of origami art, such as an origami crane mobile to hang in his home, or an origami paper lamp that will provide both a unique source of light and a visually pleasing decoration. Whatever you choose, make sure to let him know that you appreciate his love for origami and support his creative interests.
Or you can get him a star map with the date when he was born.
