Frieze carpet is a twist carpet that is a very popular trend today and is a modern version of yesterdays shag.
It is like the old shag, however, rakes are not required. The new "shag" has longer and skinnier fibers then old shag. Frieze is not as dense as textured saxony but is very durable due to the twist. (Textured Saxony is a solid color that is manufactured with fibers that are kinked and running in multiple directions that helps to hide the footprints)
