After endless exhaustive searching, we've finally found it-- the rarest gem of them all (drumroll please): recycled polyester interfacing! This fusible interfacing has been put to the test by our team, through ironing and washing on several fibres, to check its staying power and stiffening abilities. Lightweight, this interfacing is best for light to midweight fabrics to add structure and strength. When interfaced, it does add a touch of crispness, making it ideal for shirting applications, waistbands, and facings for garments that aren't too drapey. Since it's nonwoven (ie. made from a paste of fibers similar to paper), it can also be used as a stabilizer for appliques and other such applications. Best of all, you don't need to respect grainline so you get big bang for your buck!
