Hi! I did the thumbprint tree at my wedding and it was a hit! We have it hanging up in our apartment now, it's like a piece of art and so fun to look at We simply set our canvas down on a table so that it was easy for our guests to write on. We set up the ink pad, pens, and wipes on the table along with some flowers. Don't forget to provide some kind of wipe so that your guests don't have to walk around with ink on their thumbs. Our table was right near our escort cards so that when the guests were walking into the reception they picked up their card and left their thumbprint. So fun!
