|Wrapped buttonholes on a similar riding habit at The Met|
Then I wrapped and wrapped, just pulling the metallic thread off the spool as I went, until I got to the end, then drew the thread through the tiny notch, and taped the end again to the backside. This whole process takes time, and I wouldn't recommend it for anyone with arthritis or problems with their hands or wrists, because it does stress them. :-\
To apply the wraps, I couched them onto the buttonholes. The first attempt, I couched the wraps on, then tried to cut the buttonhole, but that was utter chaos, and didn't work. You have to make the buttonholes FIRST, then apply the decoration. I used a Sulky brand shiny silver thread, very thin, to couch.
I haven't dealt with the ends yet, and as Hallie points out in her post, they are problematic. It will take some clever embroidery over the top, in the metallic threads.
They look very nice when done. I seem to have issues getting buttonholes on straight, but the nice thing is that if need be, these can be easily taken off and re-applied. They add some structure to the buttonholes as well as beauty, too, so you don't have a floppy front edge. I think they will be worth the work in the end (she says now, with, like, 17 more of these to go...)
