I started at the bottom and my machine had no problems doing the first three buttonholes. But then it changed the buttonhole size completely. The difference wasn't huge so I continued but the remaining two were disastrous. One of the other things it did was to complete the buttonhole programme stitch without having stitched the hole thing. Have you ever tried to unpick a black machine sewn buttonhole on black corduroy? No, not possible. I tried but ended up ruining a bit of the lining inside.
I fudged it and managed to have a finish garment that is usable.
I can honestly say I'm a bit traumatised with buttonholes and would rather insert invisible zippers for future projects. But button looks so lovely and I definitely don't want to go off them, just because I had a bit of trouble.
So what is your experience with buttonholes/ buttons? Have you had any problems? Do you have any techniques, tips or hints that help make it easy? I look forward reading them.
