What is the difference between lined and interlined curtains?
Interlined curtains have three layers of fabric. The outer or patterned fabric that you see, an inner layer of fabric known as interlining and a rear fabric that is lining. Interlining is used to pad out a lighter weight fabric to give the curtains a fuller look or to give the curtains an extra layer to keep warmth in the room.
Sometimes the interlining is a separate layer from the lining and curtain fabric, but you can get bonded lining fabric which has the interlining bonded to the lining.
Not all curtains have interlining, but most will have a lining of some kind, to either make the curtains hang with fullness, to help to prevent the curtain front fabric from fading or to prevent light leaking into the room.
We also stock a nap lining that is brushed cotton on one side, it’s an in between version of using lining and interlining and gives curtains more body.
