A reader named Mariëlle, from the Netherlands, emailed me a photo of this wonderful Guest Tree from her Wedding!
They used a plain canvas and transferred the Old spooky tree image (although it certainly doesn't look spooky here!) onto it. Each guest placed their finger print somewhere on the tree, using archival ink, and then wrote their name in.
I think this is such a wonderful idea and something she and her husband will enjoy for the rest of their lives!
