How about getting your husband a soap-making kit? There are many options available online or in specialty stores that contain all the ingredients and tools necessary for soap making. You could also look into a workshop or course on soap making for him to learn new techniques and ideas. Additionally, you could get him some high-quality fragrances or essential oils to experiment with when making soap. If you want to make the gift more personal, you could create a custom label for his soap creations or put together a basket with different soap ingredients for him to experiment with.
Or you can get him a star map with an important date you share.
