Math Challenge: Moulage Class with Kenneth D. King / Day One

To: 

all math geniuses, 

anyone with IQ over 140, 

nerds,

pattern-making experts

Subject: "Why are you still using inches in the US???" or "solve the problem!"

Yes, it is a Moulage Class review. But I won't tell you anything about it before we resolve this mathematic problem.

(Ok, I will talk about the class a little bit: Twenty-four measurements, fraction orgy, foggy brains and five hours later, and we walked out with a custom draft of the back bodice for Kenneth D. King's Moulage Class. The class is great - fitting and patternmaking bootcamp! but...)

Back to inches! Dividing fractions is (to certain extent) masochistic. You disagree? I mean it takes just a second to divide two-digit numbers in metric system! Now do the same in inches... Piece of cake? yeah, right... Now, try to use fractions for patternmaking / calculations. It can't be as accurate as the metric system.

Here is the very first measurement we took: my neck, which, by the way, measures 13" (or 33cm). To draft the moulage, we need to make the following calculation:

1. Neck: 1/6 (neck measurement) + 1/2  = back neck

let's write it out: 1/6 x 13" + 1/2 = 2 1/6 + 1/2 = 2 2/3 (here, try now and get it converted to eights or sixteenths for the ruler units). My calculation was somewhere around 2 5/8 (it is a millimeter more, but there is no way you can get this so precise for inches ruler)

NOW, LET'S DO THE SAME IN CENTIMETERS

neck measurement : 6 + 0.5 

to remind you, my neck measurement is 13" = 33 cm

33 : 6 + 0.5 =   5.5 + 0.5 = 6 cm

Now, look at your measuring band if it contains both, inches and centimeters. You will see that these two calculations differ from each other in slightly more than 1/4" (or appr. 7 mm). 

Or, am I doing something wrong??? Yes? Then, here is your challenge: prove me wrong! (and don't think of me as another arrogant European, please! I am neutral)


EDIT: Reader Jilly B found the missing 7 mm (read her comment after you found the mistake in my calculations). Thanks, Jilly B!

But my question still remains, am I the only one who thinks that fraction calculations are extremely cumbersome in comparison? 

Plagiarism on Project Runway

Look 9 from the final collection by Andy South for Project Runway, Season 8.

Well so much about top three fashion designers on Project Runway. This design by Andy South is identical to one featured in a cult Japanese pattern-making book by Nakamichi Tomoko. Check out page 52.



By the way, if you can draft a pattern for a basic bodice and a skirt and want to try something more challenging and creative 'Pattern Magic' is for you.
