Curtain interlining is defined as a layer of cotton flannel like fabric between the face and lining of a curtain.
It makes curtains look luxurious and drape elegantly.
Curtain interlining absorbs more sound and provides greater insulation from cold and drafts.
A synthetic version called sarille can be used for lower cost but does not drape as well, works,well with eyelet c curtains to firm the pleats when hanging.
