Our fabrics are printed on linen and linen/cotton blend grounds, both of which are natural materials. These materials can have slight variation in color from dye lot to dye lot. These inconsistencies are part of the beauty of these natural artisanally woven fabrics and are not considered fabric irregularity. Our grasscloth wallpapers are also printed on natural fiber-backed paper. Because the fibers are bleached, they can change from dye lot to dye lot. These inconsistencies are not considered a print irregularity.
