When we produce additional yardage to match a prior order, we use the cutting from the first order as our sample to match to. Although variables exist that do prevent an exact match, we do our very best.
Enough wallpaper should be ordered so that the two dye lots are NOT installed side by side on a flat wall. The installer should always merge the two lots in a discrete location, such as in a corner or around a window, and order more if necessary to allow for this.
The feel of this wallpaper is so nice! I also love the colors. Please note that the background color is not a stark white, which I love, but you may want to know that before purchasing. It is definitely more of an off white/cream color.
