A range of headings can be offered (see below photographs).  Curtains are lined with a quality cotton sateen lining which protects the curtains from the sun.  Alternatively you can choose a blackout lining which helps to block out the light and make the room darker. 

Curtains can be interlined to create warmth, fullness and a beautiful drape.  I recommend full length curtains be interlined in particular and I use a wonderfully soft cotton domette interlining.
