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.
