Wallpaper collection Insero from Arte International. Follow the ethnic trend with handmade wallcovering. Arte, the wallcovering specialist, is frequently inspired by Mother Nature, be it at home, or further afield. After all, nature embodies authenticity and purity, two things that many of us hanker for. The brand sometimes goes just that little bit further too, by incorporating natural elements in its collections. Take for example our new handmade Insero wallcovering collection, in which jute plays the lead role.
