Seems like the new thing to make is a family tree using thumbprints. I recently attended a wedding where the guestbook was actually a thumbprint tree and of course I had to them make my own version. So if you know of anyone interested in creating a family tree for their family or someone getting married who wants a unique keepsake, please feel free to share this option with them. It would also make a special anniversary gift!
I can easily adjust the colors and can print names in or just leave the branches blank for people to sign when they add their fingerprints.
