Riga is a polyester fabric recommended for window decoration and textile accessories. The twill weave, also known as a diagonal pattern, yields an effect of fine transverse stripes, with subtly differing shades and a delicate tangible structure. Riga is soft, drapable and has a pleasant handle. Visually, it resembles woollen twill clothing fabrics. It has an elegant matt finish. Its 28 colour range includes black, greys, navy blue, broken shades of blue and yellow, browns, beiges, creams and white.
