Chalkboards are extremely trendy right now! To give your guests something sweet to read, display a relationship timeline chalkboard. If you want to make your own chalkboard, you can purchase chalkboard paint at a majority of craft stores.
Year Table Numbers - photos of bride and groom at the same age as they are growing up, rehearsal dinner idea. I think I would just put AGE 8 or whatever age instead of the year though. I love looking at pictures of the bride and groom at the tables.
Great idea for wedding or anniversary party. cute to do for parents anniversary. Have each guest sign a puzzle piece, put puzzle together & frame it. And bam! They have a cute guest list to remember the loved ones at the party :)
