One of the challenges of designing a commercial sewing pattern is making pattern pieces that will fit into the envelope! The most an envelope can hold is either 4 large sheets of tissue paper and 3 guide sheets OR 3 sheets of tissue paper and 4 guide sheets. So, you see the problem.
There have been times when my costumes have been changed after I've finished and turned them in, because the pattern pieces were too large or the sewing too complicated to explain in the limited space ... Martha McCain can tell you even more on this topic!
I wanted this pattern to be a cape and also a cloak with large sleeves, so I had to be very creative how I went about doing this. The secret is in the curious angled yoke seam.
So this is my chance to explain that seam and tell you how to eliminate it, if you want.
I had to make two front yokes and two back yokes, one set for sleeves and one set without sleeves so only one large main piece would be needed that gets cut 4 times. The yoke seam is slanted so much because it needs to reach low enough so that a large and complete armhole can be incorporated in that piece. Separate front and back yokes are needed because a correctly cut neckline should be higher in the back than the front.
But, you can overlap and pin the yoke pieces to the large main piece to get rid of that seam, if you want.
