Fancy yokes are not hard to do if you follow the following steps that I adapted from a Ron Collin's class. Use fine net to sew to the curved edges to finish them prior to sewing the yokes on the shirt. The net isn’t bulky which is perfect.
First step is lay the net onto the yoke piece. I make sure that it is even with the front edge and it goes up high enough to be in the armhole. On this this shirt, I stiched 3/8” from the edge and clipped the curves. Trim to 1/4".
Next turn the netting to the wrong side of the fabric and work it to the back at the sewn edges. Watch to make sure all corners are sharp. For these shirts I am adding black piping. I have pinned it on to the sewn edge of the yoke.
The wrong side of the yoke.
And then I baste the piping in place so it won’t slip when I sew the yoke on to the shirt.
I sewed the yokes together at the shoulder seam and, after pressing, I pinned them in place on the shirt body. I stitch down the neckline and fronts 3/8” so they won’t slip. I then pin the yokes down and stitch them in place.
