I know this is an old post but I have been noodling this idea for at least a couple of years and never got it off the ground. Maybe in the new year when we slow down.
Hit up your suppliers for 5 or 6 different wall vinyl sample rolls. They are usually about 27" wide I think and 5 yds long. Print the 10' wide graphic, each panel of the different material and then hang them. That way we have a side by side comparison of the different materials right there on the wall for all to see.
