Buttonhole stitch can give a really nice rustic or ethnic feel to a garment and is often seen on Mexican blouses around the neckline and bottom of the yoke and sleeves. I usually stitch it by hand, but I have noticed that several of my sewing machines have a machine buttonhole stitch. Since right now I have the old Elna SU set up, I looked up in the manual to see if any of the cam designs would work for this. Over the years I have managed to get a lot of cams for this machine and keep them in a box near the sewing machine. This time I decided to use Cam # 150. It was certainly fast to do the stitching by machine, though a little tricky over all the layers of the yoke, and I did rip sections of it out several times before I figured it out. The best part is that I could use the same thread as in the embroidery so it matches.
Above is a close-up view of the stitching along the side of the yoke. To make the top (outside) portion of the stitch more prominent, I put a row of straight stitch over it after the buttonhole stitch was finished.
Now that the buttonhole stitching is done, it is time for the neck binding, then the side seams and armhole binding.
