My pdf murals are like giant puzzles. Print out one page for each student, have them color according to the color guide, and then tape the pages together to make one large mural. Buy the template once and print as many as you want for as long as you want. All instructions are included.
My Endangered Earth Day pdf file includes two sizes:
• 9 Coloring Pages: 24″ x 24″
• 36 Coloring Pages: 48″ x 48″
