We took 4x6 unlined index cards...printed a design on the one side with the couples names and their golden anniversary date. At the top we put the heading "Written down with Love..." We embossed the heart on the design in gold.
Then at the celebration; we handed out these card and asked each guest to jot down a "Memory", story or a best wish. We then had a wooden box personalized to store these in. This was a unique way to replace the guest book and give the couple something to enjoy after the celebration was over.
