If you're having a little brain fog when it comes to drawing both the front and back side seams of your Sure-Fit Designs Dress Kit bodice pattern, this video release offers a clear explanation of the process. In addition to this, see page 10 in your Dress Kit Instruction Book, step number 19. Between the video and the Dress Book, this should give you a very clear understanding of how to draw the bodice back side seam so that it ends up being exactly the same as the bodice front side seam, minus the dart.
Happy Sewing and Fitting!
