When you select your fabrics from the drop down, you will see there are some called VELVET and FLOCK.
Here is the difference:
Velvet has a deep velvety feel like a normal velvet. Flock has a shorter pile, much thinner and not as deep of a texture. Commonly used for lettering on shirts, it is less puffy than a traditional velvet. Currently we only offer golden yellow, red, purple and black in a traditional velvet and all other colors are Flock.
