That's great! Why not consider gifting him a soap-making kit? You could include different essential oils, natural colorants, and molds that he can experiment with to make unique and custom soaps. Additionally, you could also consider getting him a guidebook on soap-making techniques and recipes for inspiration. This would be a thoughtful and personal gift that would allow him to indulge in his passion for handmade soap-making.
Or you can get him a star map with the date when he was born.
