|Fold a collar up and press - with seam allowances down.|
|With right sides together, align another collar piece as shown above, pin. Sew around the edges - notice the red thread seams (leave the bib section open for later hand sewing).|
|Remove pins. Clip corners. Turn right side out.|
Repeat for the other side.
|Make one very precise 1/4" cut in the very center (the brown fabric only).|
|Fold the raw edge of the open part under and hand sew from the center to the pink arrow.|
Of course, you do this for right and left sides of the collar!!
