This is custom Marriage Book! The couple who ordered it from me used it to write their vows in and read from during the ceremony. They plan on writing letters to each other on their anniversary each year; hence, the August 16th on the front. It also has a tree, the moon phase from their wedding day, their favorite constellations (with the big dipper on the front), and a stone closure from the place where they hiked on their first date. The collaboration and intention that put it together was as beautiful as the finished product!
