Any help anyone can give will be greatly appreciated. I am making some draperies with a blackout lining. The problem is the lining. At this stage it is still seperate from the drapes but it seems to hang crooked. It acts like fabric when it has not been cut on straight of grain. I didn't think that blackout drapery lining had a straight of grain or any grain lines to worry about. Even if it does I didn't cut it off grain in the first place and it is simple a length of fabric sewed to another half width length of backing to get the width I need for backing the drapery fabric. What could possible be making this lining not want to hang straight? Thanks in advance for any ideas.
