This wallpaper is great but I ran out of wallpaper and immediately bought a new roll and the pattern/run and color do not match. The manufacturer is not willing to help solve the problem after paying over $200 for wallpaper. It was not extremely noticeable until up on the wall. I am being told the manufacturer does not track lot numbers?! If this happens often why would you not know lot numbers on orders to help solve these issues? So now I am out $200 and lots of hours of my time. Doesn't seem right.
