Probably the most popular guestbook alternative remains the signed framed photo.
It’s pretty simple. Just have your engagement or other photo framed but the key is to have a large mat around it where people can sign.
Add pens and off you go!

For a REALLY durable alternative, you might want to check out the Titanium Inscribable Signature Keepsake Mat Kit available at our Weddingstar site. This actually is a metal mat that the guests sign, which will never fade or never rust. As strong as your love!
