Hi Linda! Do you have a Homedepot nearby?
Ralph Lauren has few products which can alter the appearance of wallpaper, such as : glazing (it will soften the appears), then there’s three other products which can tint the wallpaper to look old: tea dying, sun bleaching, etc. However, I would ask the painters in homedepot which products to use . If you are not happy with their answer , speak with the store manager, They are always helpful ! Good-luck!
