Many times after we buy Curtains for our homes we find that the curtains do not block much sun light, keep flying in the air and do not give the warmth and coziness that we require in our room. So in such cases, Lining a curtain with a cotton lining material becomes necessary. Further, stitching a lining also helps in increasing the life of curtains as the lining saves the curtain fabric from exposure to direct sunlight.
