For Nancy, of the misbehaving knit:

I don't have a direct suggestion, but the folks at Stitcher's Guild seem to be able to answer almost anything.

The golden ratio is an ancient mathematical constant that rounds off to 1.6. It is calculated by the formula (a+b)/a. The larger of the two numbers is "a". The ratio is appealing to the human eye, and can be found in nature. All you ever wanted to know about it is on Wikipedia.

In terms of this grid, the unit of measurement is a head. The top of the body to the waist is 3 heads. The waist to floor is 5 heads. Thus (5+3)/5 = 1.6. If a person happened to have a very long head, no neck and a very high waist, their proportions would be 'off.' In such a case, clothing could be chosen with a dropped waistline, and a neckline that draws the eye downward.

I remember long ago, my home ec teacher telling us that a blouse and skirt should be in the ratio of 3:5 for pleasing appearance. Nothing about a head there, but this, too is the golden ratio.

This article is all about awareness. What happens after that is personal creativity.
