It worked on the red coat. Now it's time to apply the golden buttonhole trim to the new satin coat. This time I found bias tape that was folded fewer times. It didn't make it much easier in applying the Stitch Quick glue, but I think the results are worth it.
I still need buttons. I still need to find a place besides the SAS warehouse in Phoenix that will sell me buttons in large enough quantities. Once the buttons are on, the buttonhole linings will make a lot more sense.
