We love sewing cotton velour nap up. Colors, especially black, are richer and darker and many of the faults found in today’s weaving and dyeing are well hidden. With Inherently Flame Resistant (IFR) fabrics like Prestige, we find the same is true. Charisma, however, seems to work well in either direction. Serge has no real nap, so for up and down it’s much the same. Even though it is more expensive, many Broadway designers are starting to use Serge (wool – which is common in Great Britain) over velour (cotton – which is a big US product). US customs tacks on a 25% import duty on Serge to protect the American cotton industry.
