How It Works

A circle skirt is cut as a donut shape — the inner circle is the waist, and the outer circle is the hem. For a full circle skirt, the waist radius = waist / (2 * pi). Half circle skirts use less fabric but have less flare. Let the cut skirt hang for 24 hours before hemming, as the bias grain will stretch and the hemline will become uneven.
