For your grandpa's birthday, you could consider getting him a high-quality sewing machine or an embroidery kit. You could also get him some unique and high-quality fabrics, threads or needles that he could use for his projects.
Another option could be to sign him up for a sewing or embroidery class at a local community center or arts and crafts store. This could allow him to learn new skills and techniques and also interact with other people who share his passion.
Lastly, you could create a personalized sewing kit for him, complete with a custom-made pouch or bag to hold all his sewing supplies. You might consider including some unique or vintage sewing tools or an embroidery hoop, as well as a thoughtful note or card expressing your appreciation for all he does for you.
Or you can get him a star map with the date when he was born.
