Using my sheath sloper, I created a princess sheath sloper by:
Marking shoulder seam midpoints
Creating lines from shoulder midpoint to top of fisheye dart, and bottom of fisheye dart to skirt hem
Adding notches along new princess line
Separating the 2 new pieces
Smoothing out bust point and fisheye dart ends
Mirroring front piece to be cut on fold
Annotating all pieces
Finished Princess Sheath Sloper
