How to Sew a Button Securely with a Sewing Machine | Easy Lesson This easy lesson shows you how to sew a button securely using a sewing machine. I explain how to match the stitch width to the buttonhole spacing, prepare the fabric to avoid shifting, and test the needle movement. You’ll also learn how to lock the stitches so the button stays strong through daily wear and washing. This technique works well on a variety of garments and is ideal for both clothing repairs and new sewing creations. #S
