Medium Weight Interfacing

Medium weight interfacing such as Bobbin Girl's Value Medium or Vlieseline F220/304 are non woven fusible interfacings, they give strength and sturdiness to fabric and is ideal for making cotton bag handles and for fusing to heavier weight fabrics such as denim and tweed.  For cotton fabrics which have a tendency to crease, Bobbin Girl suggests avoiding medium weight interfacings and recommends using a Bobbin Girl's woven interfacing instead
