How It Works
Interfacing adds structure to collars, cuffs, waistbands, button plackets, and facings. Fusible interfacing is ironed on and is the most common. Sew-in interfacing is better for delicate fabrics. Interfacing is typically sold in narrow widths (20 inches) so you may need more linear yardage than expected.
