When brainstorming ideas for a wedding guestbook, I came across a bench that all the guests signed. It was a brilliant idea! I got all my bridesmaids together and had them help me build Ana White's Rustic Bench (plans here:
http://ana-white.com/2010/01/plans-rustic-be...), painted it white and added some custom artwork with a paint pen. At the wedding, all the guests signed it, and I sealed it with polycrylic. It's the perfect heirloom piece, and our guestbook is displayed at all times at the foot of our bed! Not bad for only spending about $15 ;) Details on how I added the artwork can be found here (http://www.killerbdesigns.com/wrapping-it-up/)
Love this idea, very original!!!
