✨ The Fun Behind This

Why It's Fun

Circle skirts use geometry: waist = inner circle, hem = outer. Full circle = max twirl; quarter = minimal flare.

How It Works

Enter waist, length, skirt type (full/half/quarter). We compute waist radius, outer radius, fabric yards, and pattern dimensions.

Key Insights

  • ●Waist radius = C/(2π×f). Full circle f=1, half f=0.5, quarter f=0.25.
  • ●Full circle uses most fabric. Dancers love it for maximum twirl.
  • ●Add seam and hem allowance before cutting.

🎲 Fun Facts

📐

A full circle skirt uses the most fabric but creates the iconic 1950s swing.

— Sewing

💃

Dancers love full circle skirts—the 360° cut allows maximum movement and twirl.

— Costume

✂️

Fabric efficiency: laying a half-circle pattern uses ~78% of a square.

— Pattern cutting

A circle skirt is made from a circular pattern. The waist is the inner circle; the hem is the outer. Full circle = 360°, half = 180°, quarter = 90°. More circle = more flare and twirl!

📋 Key Takeaways

  • • Waist radius = waist ÷ (2π × fraction)
  • • Full circle = maximum twirl, most fabric
  • • Quarter circle = pencil-like, least fabric
  • • Standard fabric = 45" or 60" width

✂️ Sewing Facts

📏Waist radius = C/(2π) for full circle. If waist = 28", radius ≈ 4.46". Add length to get outer radius for the hem.Source: Circle geometry
