With right sides together, align center BACK with the bottom back of HOOD where seam 3 ends.
Pin seam 4 hood to seam 4 cloak.
Stitch from center of the back to the front on each side. (Starting in the middle of the seam and sewing to the edge on hoods and collars helps to keep the ends even.)
Hem all the way around the cloak and hood with one hem.
Cloak With Lining
For a lined cloak, repeat all of the above a 2nd time with your lining fabric. Pin the two cloaks right sides together. Stitch around the outer edge, leaving a small opening to turn the cloak right side out through. After turning the cloak right sides out through this opening, sew up the opening by hand.
