If you sew with Burda Sewing patterns you know they call for Vilene Iron-On Bias Tape on many garments. This stuff will help your garments retain their shape and is essential for stabilizing necklines and armholes on all sorts of garments. I am stocking this item at www.stitchnerd.etsy.com. This is what it looks like and I carry it in white and charcoal colors.
