Medium Weight Interfacing

Medium weight interfacings like Bobbin Girl's Value Medium or Vlieseline F220/304 are non woven and fusible. They add strength and structure to fabric, making them ideal for cotton bag handles or for use with heavier fabrics like denim and tweed. For cotton fabrics prone to creasing, Bobbin Girl recommends avoiding medium weight interfacings and instead using a woven interfacing for a smoother finish.
