Love this product! It was super easy to put up. I did it by myself in about 3 hours. It’s so easy to pull up to readjust and fix. The pattern is a little tricky, but that’s what makes it so beautiful. Ordering the 10% more gave us enough with a little left over, however I had to get a little clever to make sure the pattern would continue to match. I almost had to order an extra roll (this wall required two rolls). So I would suggested adding more than the 10% extra or just buying an extra roll to make it a little easier on yourself.
