Last time I made this pattern, I put some lace trim around the front yoke, but this time I am going for a more Mexican look, so I am putting buttonhole stitch around the yoke. The neckline is finished with bias binding, and I am putting in a placket or opening in the center back which will close with a button and loop closure. The yoke front lining is cut from an IKEA Knoppa sheet. Those sheets are great for linings, being a light batiste-type fabric which feels great and is easy to work with. Not to mention the cheap price for lots of yardage ($1.99 for a twin sheet).
In order to avoid finicky seaming, I turn the edges of the yoke under and baste it down to the rest of the blouse, then topstitch it down close to the edge. The lining is sewn in by hand and is held flat by the second row of topstitching (which provides a convenient guideline for the buttonhole stitch). Those Knoppa sheets are really easy to hand stitch and are a pleasure to work with.
