Flock is a word you know as a number of birds together, or congregants at a church, or sheep, or tourists. I don’t blame you if you don’t know the fabric definition—it is often missing from regular dictionaries. Flocked fabric Flock is the name given to very short fibers, either from fabric-making waste or created from rags. A flocked fabric is one on which flocking has been applied with an adhesive, either all over or in a pattern. A common flocked print is dotted swiss. Any fabric weight can be used. Flocked fabrics have improved, but the all-over flocked (velvet-like) fabrics can be fairly stiff. Flocking also has the tendency to wear off. Uses: Dresses, household decoration, aprons Flocked cotton organdy Flocked cotton voile This is a flocked point d'esprit veil. Point d'esprit is a fine net with small dots spaced evenly all over. While the best quality dots are embroidered, they can also be flocked or woven with the net itself. You may have run across one of these point d'esprit veil hats This is a flocked version of dotted swiss, made of polyester. (I have had this fabric since the late 1970s! I made a sort of smock dress out of it back then.) Note in the comments that flocking isn't the only way of making dotted swiss. In the 1950s flocking could be quite elegant, to my eyes especially black flocking on black taffeta, like this skirt. This is a flocked acetate taffeta from the 1950s But you can see the way it wears when you look at this skirt. I couldn't sideline it because of those dancers, but it was definitely worn.
