We purchased a garage mural and it was too long. I simply measured the distance it was over and divided it by two. With a sharp box knife, I cut each side very carefully the amount it needed to be shortened. Then with a hole punch I punched the 2 holes at the top for the bracket. I used the piece I cut off as a guide so I knew where to punch the holes. I did the same for the bottom single hole for that bracket. It worked out great. Looks amazing! I am over the moon excited to see it with our other decorations! We do large candy canes and oversized peppermints which goes perfectly with our new mural!!!! Try it, it works
