Circle Skirt pattern

To create a circle skirt you’ll need the radius of a circle where the diameter is your waist circumference. diameter = 2Piradius waist circumference (waist_circ in Valentina) = 23.14radius = 6.28*radius radius = waist_circ/6.28 This circle skirt is completely resizable because it uses control handles for the curves, and doesn’t use any absolute numbers except Pi. The curve’s control handles are 1/3 the length of the line between the curve’s segment end points, and they are perpendicular to th…
