I just adore these alternative guest books—puzzles that Etsy vendor Lara Braithwaite promises will challenge and amuse you long after your wedding—by Bella Puzzles Too.

To make your-one-of-a-kind guest book, Braithwaite takes your photo, names, a date or a quote and hand-saws a slab of birch wood into a tricky little jigsaw puzzle. Guests sign the back of each piece, giving you something special to read each time you put the puzzle together.

Puzzles with enough space for 25 signatures start at $60, while a puzzle fit for nearly 300 guests can cost up to $600, according to Braithwaite’s site.
