This video focuses on adjusting the armscye of a bodice block. Izzy explains that the armscye, while initially a basic circumference, often needs adjustments for a proper fit.

She begins by explaining how to identify armscye fit issues. A tight armscye will cause puckering and discomfort under the arm, while a low armscye will reveal excess skin. Izzy recommends marking the desired armscye line on a toile and then snipping the fabric to test the fit.

The video then transitions to the pattern alteration process. Izzy demonstrates how to measure the difference between the existing and desired armscye depths on the toile. She emphasises the importance of identifying the point where the armscye no longer needs alteration.

Izzy then shows how to transfer these measurements onto the paper pattern for both the front and back bodice pieces. She demonstrates how to mark reference points along the armscye curve at regular intervals, measuring the offset distances from the original armscye line.

Izzy then demonstrates how to redraw the armscye curve, connecting the marked points to create a smooth line. She emphasises the importance of using a pattern curve ruler or eyeballing the curve to achieve a natural shape.

Izzy concludes by explaining that the same principles apply whether raising or lowering the armscye.
