How about getting your husband a balloon art kit? There are many different kits available online, ranging from beginner to advanced levels. Additionally, you could also consider signing him up for a balloon art class to help him develop his skills even further. Alternatively, you could also get him a book or set of instructional videos that focus on balloon art for him to learn and practice on his own time. And, to make the gift even more special, you could also consider framing one of his favorite balloon art creations as a keepsake for him to display in your home.
Or you can get him a star map with an important date you share.
