"Pythagoras pants on all directions are equal to" + circumference length. Everything. No steps. In short, it sews such an elegant long skirt almost without pattern. Calculations:
The author of the author had to sew the evening to go to corporate in it tomorrow. She wanted a skirt-sun, but there she should be shifted to hang up ... I had to experiment:
2.
"Figure 1 - Skirt cutting diagram. Crow lines are shown blue. Everything is based on squares.
The sun from the square would have turned out to be multi-level: short-lived in direct areas and long in diagonal. And I wanted a long skirt, so I decided to instruct the short sections of the skirt with small triangles to the length diagonally. The height of these small triangles (in the figure of the AC) is defined as the difference between the hypothenus length of the Bolshoi triangle AO and the length of the category (s, OS).
By the theorem of Pythagora AO = √ (2 rs2)
I took a 150 cm width fabric. I have ov = 75 cm. JSC = √ (2 * 752) = 106 cm.
It means that the required height of the triangles of the AC = AO - OS = 106-75 = 31 cm.
Next, by the same Pythagore theorem, we define the karts of small triangles, i.e. The length of the feed line to the main skirt feather.
Hypotenus AA1 = 2As = 62 cm.
AD = √ (AA12 / 2) = √ (622/2) = 44 cm.
Thus, with a crop according to the scheme in Fig. 1 and the width of the fabric 150 cm, the flow rate of the tissue, taking into account the allowance, will be 2 meters.
Next, we drag small triangles into the main canvas, as shown in Fig. 1. We combine an orange line with orange, pink with pink.

four.
But! Next, there is one nuancenchik, about which I learned already in the first hour of operation of the skirt: when driving, the fabric turns out from the inside, and it turns out like this:
five.
To avoid this, I connected the corners of the adjacent Fald ribbons from the inside (in fig. 3 ribbons are shown in a pink dotted line, blue dashed line - FALD seams).
6.
This circumstance, I will not hide, I upset me somewhat, because The skirt from this ceased to be ingeniously simple. But for the convenience of iron, these ribbons can be provided on the fastener.
But nevertheless, invented by me, "Bicycle" goes, so the right to life has: the cut is simple, and all the seams of skirts are obtained at the direct direction of the thread, the entire line of Niza is on oblique. "
