Papillon Blueberry Wallpaper, Half Scale - 1/2" SCALE WALLPAPER SHEET SIZE: 5-1/2" X 8-1/2" - All wallpapers are printed on acid-free, archival stock. The one inch papers are heavier weight than smaller scales for easier handling. Although color reproduction is as accurate as possible, it may not be an exact match due to variations in monitor set-up. It can be helpful to spray papers lightly with a sealer such as as Krylon Matte, available in art supply or craft stores. Use a good quality wallpaper paste, work neatly and avoid rubbing print side while wet.
