Then, each year on your anniversary, take a picture of just you and your spouse doing something fun.
Slip a print of it into the box, along with notes sharing marriage highlights from that year.
Register for one and experience your first evening of painting together on your anniversary.
Or watch an online tutorial about painting with watercolors or oils.
While on your picnic, take a picture of the two of you.
Plan a day-long adventure with your spouse—a hike, bicycle ride, hot-air balloon ride …
Create your own "masterpiece" together of a favorite memory while playing romantic music. After an out-of-the-ordinary meal, talk about the hopes and dreams that you have for your life together.
