The buttonhole stitch is the most appropriate stitch for sewing buttonholes. It is used to prevent fraying of the buttonhole. Since it has a small half-knot at the top of each stitch it is also less likely to unravel if the thread is broken, something that is likely to happen eventually, from use. To get the most strength, it is important to wax the thread before use. The waxing will strengthen the thread and prevent twisting while sewing the buttonhole, the buttonhole stitch in any direction. Following is the procedure of doing buttonhole stitch. Hold the thread along the top edge of the material, with the end pointing in the direction you are going to sew. Make a loop with the top of the loop pointing upward. Inserting the needle through the loop, then into the fabric from the wrong side and then through the large loop left on the right side of the material. Tighten your stitch, keeping the purl on top by see-sawing the thread and using your fingernail. The additional stitches are created by arching the thread over the right side opening of the buttonhole in the direction you are sewing, then looping down and back around in the opposite direction your are sewing, through the loop at the top, then through the material from the wrong side about 1/16th of an inch from the last stitch, through the large loop on the right side and then tightening as before. Continue doing this all the way around the buttonhole until done that’s how the buttonhole stitch embroidery is done.
