Fusible interlining bias tape from German Freudenberg.
The tape is 12 mm wide and comes in two colors: white or charcoal.
The tape is cut on the bias, which allows you to shape it. It has a safety stitch a little off to the center, which keeps the length of the tape, once ironed on.
Add to the wrong side of the fabric in the seam allowance, to prevent a cut line from growing while handling the cut pattern parts. Perfect for securing necklines and other curved design lines, which you want to be able to control.
How to use: Dry iron, medium heat, press for 8 seconds.
