VELVET:
There is a nap to the fabric after cutting the loops. Running you had in one direction will be smooth while going in the other direction you will feel resistance crushing the nap. This also will appear to change the color of the fabric.
Velvet does not wear will, just like silk. Moisture is a big enemy of velvet, as is crushing. Velvet gives off a beautiful luster. Cotton velvet is more suitable for upholstery because of it's durability ( weight, heavier and luster), but for heavier use furniture it should be avoided. Professional cleaning delivers good results
