Turn your engagement photo (or other awesome photo of you two) into a one-of-a-kind guest book for the big day. Have guests each sign a piece OR assemble first and have everyone sign it like at traditional guest book (better if you want to allow messages because there is not a tremendous amount of room on a single puzzle piece) but take it apart before delivering to the newlyweds so they have the fun of putting it together to read what everyone wrote.
Actual piece counts for popular guest book sizes:
100 piece - 104 pieces
175 piece - 176 pieces
Sample shown in 175 piece size with 156 blank pieces - let us know if you need your image sized a certain way to be sure there are enough pieces for each guest.
