This (short) post will help you to trace pattern pieces and join them in correct order. Each traced piece is color coded, I am showing how to join the pieces for one half of the skirt. The other half should be done as a mirror image.
On the piece 2 (center back), you will need to join the three traced pieces (orange piece was traced on fold). The seam with two notches connects to the side back. Three notches are used for the center back seam. One notch is used to indicate side seam.
Placement of the grainlines (blue lines on the illustration) was discussed in Part Two. The center back grainline divides the pleat (the purple piece) in two equal parts. For the side back grainline divide the waistline and hem sections in half and draw the grainline through those midpoints.
Let me know if you have any questions on the Couture Collective forum, or post a comment here.
