Wallpaper is an old-age term given to materials that are more typically included in the category of wallcoverings. Very few modern wallpapers are actually made of paper anymore. Today's wallcoverings are made of vinyl, fabric, grasscloth, metallic foil, cork, plastic, cardboard, 3D tiles, shells, embossed materials, and many more! We have even done custom wallcoverings made out of sheets of metal! How cool! (see picture on the right).
With that said, please do not limit your choice to only wallpaper, we suggest you start thinking outside the "paper"!
