One idea could be to create a customized crossword puzzle for your wife, using clues and answers that are meaningful to your relationship. You could also consider purchasing a book of crossword puzzles or a subscription to a crossword puzzle service, so she can enjoy new puzzles regularly. Additionally, you could purchase a crossword-themed gift, such as a crossword puzzle mug or a piece of crossword puzzle jewelry.
Or you can get her a star map with the date of your anniversary.
