For bias tape, use store bought tape or tape youâ€™ve made. Either way, it should be wide enough to encase the cord and leave enough fabric to be sewn into the garmentâ€™s seam allowance.
For this tutorial, this cord is 1/8â€³ wide. Th bias tape needs a seam allowance of 5/8".
To ensure the tape is wide enough, double the width of the cord (2 x 1/8â€³) and double the seam allowance (2 x 5/8â€³). Added together, the total amount is 1 1/2â€³ for the width of this bias tape. For your custom bias tape, follow this little math equation:
(2 x cord width = _____ ) + (2 x seam allowance = _____ ) = total width of the bias tape.
Note: If the final seam allowance is a little short, donâ€™t worry! Simply mark the seam allowance line on your garment and match up the finished piping by pinning in place.
Place the cording in the middle of the bias tape strip. The wrong side of the fabric should be facing the cord.
Fold the tape over the cord. Pin in place with both edges of the bias tape matched up.
Baste the cord to the bias tape at each of the short ends before you sew to prevent accidentally pulling it out.
Attach the zipper foot to your sewing machine. Place the cord as close to the needle as possible. Sew slowly, making sure to keep an even line close to the cord.
