Part 2 Fronts
The sewing pattern is available via Etsy.
Gather the sleeve head with two rows of a running stitch. Pin into the armhole, right sides together, spread the width evenly between the marks and sew.
Prepare the yokes. The sewing pattern shows the yoke as one piece without seams; here I made it from two pieces, because the yoke often was made from pieced rests. Turn in all seam allowances, except at the side seam. Notch were needed, at corners and curves.
