I wish I aged this well since 1977!
That is the collar at the top of the picture.
This time I made the front button facing in a contrasting color and so a glimpse of it is seen when the collar folds down.
Doing the buttonholes always makes me nervous as they run right up the front of the garment and if I wreck this last feature I have wrecked the whole shirt, so I always go carefully and slowly on this.. and sew with my fingers crossed and my teeth clenched a bit.
All Done. I like it.
