The inclusion of even a small percentage of man made fibre will cause a
fabric to give off direct reflections and glare as you change your
lighting position, or at least that has been my experience. If one wants
only diffuse reflection stay with 100 otton ....... avoid the
inclusion of even a small amount of polyester at all costs!!
