How about getting him some high-quality leather to work with? You could also consider getting him a leatherworking kit that includes all the necessary tools and supplies he needs to create his own leather goods. Another option could be getting him a gift certificate so that he can take a leatherworking class or workshop to further develop his skills. If he already has all these things, you could look for unique and interesting leather pieces that he can use to add decorative touches to his projects. For example, leather buckles or fastenings, metal studs, or even leather scraps in unusual colors and textures would make great additions to any leatherworking project.
Or you can get him a star map with the date of your first kiss.
