I hung the 4' x 8' poster on the wall of my restaurant. Before I was even done taping it down I had people from teens through preK coloring away.
Last year my son's school put up the mural for students to color. My son has been talking about it since and is incredibly excited to do it again this year.
Everyone in our family spent the whole morning coloring the poster. We all love it so much and had a great time!
