My in-laws are celebrating their 40th Anniversary next month so we're planning a party (and possibly vow renewal if I can convince my father-in-law to go along with it). There won't be more than 50 people there. I'd like to have some sort of guest book for them as I think it'd be a nice gift and keepsake from the day. I'm looking for suggestions for an alternative guest book, not a traditional book people sign. Any ideas?
I found a print of a tree on Amazon where you can put your thumbprint and sign, but the quality isn't the best. Any suggestions (especially links or pictures) are greatly appreciated!!! It will be outside at a state park; more low key and rustic than anything.
