For your husband's anniversary gift, you could consider getting him a balloon art sculpture. You could even have a personalized sculpture created just for him that incorporates his favorite things or even a special message. Another idea could be booking a balloon art class or workshop for the two of you to take together. This could be a fun and unique way to spend time together while exploring his interest in balloon art. You could also consider purchasing a kit with instructions and materials for creating balloon animals or other creations for him to practice his skills.
Or you can get him a star map with the date of your anniversary.
