PrestoTex self-adhesive wall media will hide wall imperfections. The media can be directly purchased from the manufacturer, and it's made in the USA. Skip the middleman, and get PrestoTex right from the people who make it.
PrestoTex is superior in thickness to Photo Tex, GraphiTex, and other polyester fabric wallcoverings. It makes it easy to print, handle, and hang. And it covers all those bumps and bruises in the walls.
