I finally finished this project. I ended up just making my own tree file, after failing to find a specific one I was searching for.
I made the ruler and applied the vinyl a few months ago. I finally got the ruler on the wall today. I plan to hang pictures of the grandkids all around the ruler. I only have one grandson right now, with twin boys on the way, courtesy of my son and daughter in law. I also have two daughters to hopefully contribute at some point too!
