    • If using the existing button, you may have to cut it off and move it slightly to be centered in the larger buttonhole and resew it on.

    • Very near the place where your button was originally sewn on, center your button in your adjusted buttonhole. Using chalk or a pin, mark this location.

    • Sew your button on.

    • Check to make sure it fits through your adjusted buttonhole well.

Conclusion

A sewing machine with a buttonhole presser foot is ideal, but this project can be completed with needle and thread.
