Examples are also known of rugs woven in the Ushak area whose fields are covered by ornaments like the Cintamani motif, made of three coloured orbs arranged in triangles, often with two wavy bands positioned under each triangle. This motiv usually appears on a white ground. Together with the bird and a very small group of so-called scorpion rugs, they form a group of known as "white ground rugs". Bird rugs have an allover geometrical field design of repeating quatrefoils enclosing a rosette. Although geometric in design, the pattern has similarities to birds. The rugs of the white ground group have been attributed to the nearby town of Selendi, based on an Ottoman official price list "(narh defter)" of 1640 which mentions a "white carpet with leopard design".
