This is Luke's JJ Industries cotton fabric with an added coating of shiny black acrylic, which is inspired by Kylo's surcoat and cowl from TFA. This is the best available and sold by the yard. It takes a little over 4 yards to complete a large Kylo surcoat and cowl with a double thickness hood and good sized cape/shawl. You might be able to get away with 4 yards if you cut it efficiently, but I would probably recommend 5. The width is 51 inches or 130 cm. You can also order the fabric uncoated and do it yourself. I only apply the coating after the order is placed so it will not ship until the coating is complete and the fabric has fully dried.
