Things You'll Need
Instructions
Cut two strips of fabric 1 inch wide and the length of the circumference of the armhole.
Match the binding edge up with the garment armhole edge, right sides together, making sure that the strip goes to the edge of the fabric.
Sew the binding to the armhole using a machine straight stitch, sewing 1/4-inch from the fabric edge. Sew all around the armhole.
Fold the binding over the top of the seam, covering the raw edge of the fabric. A 1/4 inch of the binding fabric should show on the front side of the garment fabric, the rest should be folded back to the inside -- wrong side -- of the fabric.
Fold the edge of the again binding inside 1/2 inch, hiding the raw edge and creating a folded edge on the inside -- wrong side -- of the fabric.
Sew the binding to the garment again, sewing on the seam that you made in Step 3 on the right side of the fabric. You will be sewing the folded binding on the inside -- wrong side -- of the fabric to the garment at the same time.
Sew the other armhole's binding on as above.
Sew the side seams as per the pattern instructions.
