  1. 1

    Measure your armpit from the top of the armpit to the bottom. Write down this measurement.

  2. 2

    Lay out the pattern, and position the French curve against the armhole. Use the rounded part of the French curve to do this.

  3. 3

    Trace from the top of the French curve down to where your measurement ends. If you measured 12 1/2 inches, stop tracing at 12 1/2 inches on the French curve.

  4. 4

    Remove the French curve and stencil in the tracing marks darker. You are now ready to move onto your next drafting step.
