Question: how do you tell the difference between woven and non woven interfacing?
Answer: Difference between woven and non-woven interfacings It's rather obvious when you look at it : The woven kind is a cotton fabric with one side (the rough one) primed with fusible glue. The non-woven kind consists of agglutinated and compressed fibers and one side (the rough one) is primed with fusible glue.
