Stabilising elastic - ideal for stabilising the scallop edge of lace cups to stop them stretching out. Use a three step zig-zag, set to almost the width of the elastic, to attach it to the inside of the lace just below the scallops, not stretching the elastic as you sew.
The 10mm width is also useful for the shoulder seams of your knit tops for stabilising.
