Poster instead of Guest Book

We're doing a poster as well! We're planning on something along the lines of "Please sign anywhere on our guest-map" (because we have a world map)

Our guest-map!

There are plenty of signs you can buy or make that simply says "Please sign". Even if it says guest book, most people get it. We had a sign that said "Our puzzle would not be complete without you. Please sign a piece." for our puzzle guest book. Our son and future daughter-in-law will be using an illustrated copy of Harry Potter and The Sorcerer's Stone. As long as you put it in a prominent place with pens, most guests get the hint.

I had jenga blocks as well as my wedding guest book and made a sign saying something like,

sign our book

sign a block

with your name

or a sweet thought

It was way fancier than this, lol but I did a little poem thing. I love my jenga blocks by the way, they are super cool to play with and read them ever now and then.

We had a guest tree sketch and just asked very simply and literally for guests to sign a branch on the tree. I wouldn't overthink it because people will get what it is and know to sign it.
