Walk the side and shoulder seams to true the connecting lines, then add seam allowances and all necessary pattern markings.

Determine the minimum neckline opening for a pull-over design based on head circumference.

Draft the back armhole princess seam, absorbing the back waist dart to create two back panels.

Rotate the front side-bust and waist darts into a new armhole princess seam line using the slash-and-spread method.

Separate the block into four distinct panels (Center Front, Side Front, Center Back, Side Back) and true the new seam lines.

Transfer all fit adjustments from the muslin back to your paper pattern pieces, finalizing the design.
