Convoluted Sheet

This shape is half of a circle. Its width (“DIAMETER”) should be twice its height (radius). If you measure your shape and find that the height (radius) is longer than half the width (diameter), use the “Pattern Shape” shape instead. Use the Pattern Shape if your shape is not an EXACT semicircle (if it’s not exactly half of a circle, or if it’s part of an ellipse), to send us your own pattern.
