The whole purpose of drafting circles comes in real handy for making skirts and cloaks. Oh, sure, you can gather a gigantic rectangle of fabric into a waistband, but do you

So, because I've thought about publishing this for a long time and someone finally asked me, here's the process I use for drafting a circle pattern. We're doing a cloak in this example, but substitute "waist" every time you see "neck", and everything else is the same.

The steps for making a circle cloak - or any fraction thereof - are pretty simple, but you're going to have to reach back to high-school geometry. It all revolves around one equation:

In other words:

Circumference (neck size) |
= | 2 * 3.14 * R |
(which will be the radius of the circle we'll be drafting) |

Size |
Multiplier |

Full Circle | Neck size (as is) |

Half Circle | Neck Size * 2 |

3/4 Circle | (Neck Size / 3) * 4 |

So, for a half circle cloak with a neckline of, say, 20", we get this:

- 20 * 2 = 40 (or
**C**) - Subsitute that into the equation: 40 = 2πR
- 40 = 6.28R (calculate 2 * π)
- R = 40/6.28 (calculate the radius by dividing 6.28 by 40)*
- R = 6.37

For convenience, and because it's easier to take something in than let it out, we'll round up to the nearest quarter and call it 6.5". (Always round

That's pretty much all the math we'll need for now. On to step 2.
