A closure clasp on a jacket is often over-sized to add distinctive character and charm to the jacket. For example, a toggle clasp in the center of your jacket works as both a functional clasp and an eye-catching focal point, serving to close a jacket instead of the common button. After you've finished sewing a jacket, add one or more jacket toggles as decorative flourishes. Sewing a toggle on a jacket involves following a few simple steps.
Lay your jacket flat on a work surface with the front facing up. Bring the two front edges together, matching the corners and edges in the way you will be wearing the jacket. Depending upon the jacket style, arrange it so that the edges overlap slightly or meet perfectly in the center.

Place the toggle clasp on the jacket where you think you want it, making sure to line up both sides perfectly. Generally, the loop side of a toggle clasp should be on the right side of a woman's jacket. Pin the toggle in place on both sides of the jacket.
Thread the needle with a 12-inch length thread. Pull the thread through the needle to make a double length of thread and tie the ends in a knot.
Insert the needle up from the underside of the jacket fabric and pull it through until the knot stops the thread. Stitch the toggle in place by taking four or five small stitches over the base of the toggle. End the stitching with the needle on the underside of the fabric and tie a knot. Clip off the excess thread.
Tie another knot on the ends of the threads and stitch the other side of the toggle clasp to the other side of the jacket in the same way. Knot the thread when you finish stitching the toggle and cut off the excess thread.
Remove the pins and try the jacket on to make sure the toggle clasp aligns and fastens properly.
