Today for the first time, I learned how to do buttonholes. I have the Pfaff 2027. While the buttonholes looked nice, they didn't always come out the same size. I did use the automatic buttonholer. I was making holes for 1" buttons. Sometimes the buttonholes came out shorter than intended. I don't know what I did wrong. I didn't move any settings. My sewing teacher was practicing on my machine, and it happened to her too.
Any advice/thoughts? Thanks!

I have a different model pfaff, but I will tell you some things to watch for:
1. thickness of fabric. If you are working with a heavy-weight fabric, or trying to buttonhole over multiple layers of seam allowance, you need to watch carefully. Specifically, the buttonhole foot might have problems feeding the fabric properly and you end up with one or both legs shorter than they should be. One way to work around this is to sew SLOWLY and maybe assist the machine in feeding the fabric. I sometimes run into this doing buttonholes on waistbands of heavier pants fabrics.
2. Trying to buttonhole very close to the edge of the fabric. If the sensormatic buttonhole foot does not have a good "bite" on the fabric, it will have trouble moving the fabric along and keeping track of where it is (i.e. the "automatic" part of the buttonhole.)
3. Confusing the machine by lifting the presser foot in the middle of the buttonhole to reposition the fabric. With these "sensormatic" type arrangements, the machine is trying to keep track of it's position in the buttonhole. If you stop partway thru and lift the presser foot or mess with some settings, you might be confusing the machine. Also, if you finish one buttonhole prematurely, the machine might not realize you want to start over. My pfaff has a "stitch reset button" to start over but if you don't have one, you could just switch to straight stitch and back again to reset it.
4. Make sure your needle is in good shape: sharp, not bent, etc. If the needle is having trouble getting thru the fabric layers because it's in bad shape, that could throw things off.
Before you run off to the repair shop, I would put together some lightweight cotton fabric layers with a light interfacing and do several buttonholes keeping these issues in mind. If you can NOT consistently generate good buttonholes under these "optimal" conditions, then you might really have a problem.
