I've admired the painterly wallpaper by Porter Teleo and the admiration was reinforced while fabric shopping at the Martin Group in the Boston Design Center. The large format hand painted wall covering is modern and also seems ancient somehow.
The fabrics are amazing as well.
Porter Teleo is a line of hand printed and hand painted wall covering and fabrics developed by artist Kelly Porter and interior designer Bridgett Cochran. "The product enlivens the best of fine art and high design, presenting a bold, distinctive color palette with refined aesthetic." This is achieved through methods of fine art processes, such as woodblocking and painting and a special printmaking technique called chine-colle. The style references ancient Japanese screens, architectural ornamentation and Ms. Porter's painterly hand.
You may recognize these products in Kelly Werstler's work. I understand why she is a fan and I see it's influence on her own fabric line for Groundworks.
The graphic element combined with the artistic hand has splendid results.
