How about a book or a kit that includes instructions and materials for him to learn a new traditional craft? You could consider:
1. A weaving kit: which could include a small loom, a variety of yarns, and instructions on how to create different patterns and designs.
2. A leathercraft kit: which could include leather strips, needles, thread, and instructions on how to create different products such as a keychain, a wallet, or a belt.
3. A pottery kit: which could include clay, pottery tools, and instructions on how to make different types of pottery pieces.
Alternatively, if you are looking for something more personalized, you could consider a gift certificate for a class or workshop in a traditional craft that he is interested in. This would give your grandson the opportunity to learn from a professional and hone his skills in a particular craft.
Or you can get him a star map with an important date you share.
