I know what's holding me back - fear of doing the wrong thing. Because I haven't done this before, I'm not sure where I'm going. But I do know that once I've made a buttonhole, it's there forever.
Here I am, laying out the jacket and thinking it should have only four buttons down the front and not the five I have put on previous jackets. The buttons are larger and the buttonholes will be more prominent so it may be too much to put all five buttons on. And no, I'm not doing this because I made one of them too dark - I can easily go get some more button forms to remedy that.
So I made the first buttonhole at the neck. And it looks good on the outside! But if I don't always button the jacket up to the neck, you are mostly going to see the inside of it...
... which looks huge, at least to me. I am thinking about running a bit of zigzag machine stitching around the buttonhole from the inside, knowing it will hardly show on the outside because of the type of fabric this is. The machine stitching will make the buttonhole sturdier and may cover up some of that floral fabric. Other than this issue, I have tried on the jacket and it fits nicely and feels even better, so I am pleased with it and I suppose I shouldn't worry about 4 buttonholes or 5.
