A great Christmas gift idea for your boyfriend who likes wood carving is a wood carving kit with different tools and materials. You could also consider getting him a book that features different wood carving designs and techniques that he can reference and try out. Another idea is to see if there is a local wood carving class or workshop that he could attend, or even purchase a gift certificate for him to take a class in the future. Lastly, a nice piece of wood for him to carve and create his own masterpiece would be a thoughtful and personal gift.
Or you can get him a star map with an important date you share.
