I shared the guest book tree earlier- here it is in action at the wedding!
I also made some wedding mad-libs for the guests to fill out. We put them in a binder during dinner and the collection was handed around and really enjoyed.
All we did for this was buy card stock for $8 and print them on our home computer.
Aside from both of those we put these on the 4 tables. We asked people to write messages for the 1st, 2nd, 3rd, and 4th anniversaries… so easy to prepare!
