Pattern ball - easy and simple
In some cases, when doing something or in needlework, it may be necessary to make a ball of a certain size and diameter. Just take it and make it unlikely to work out. This requires accuracy. To get the right product, you must have a ball pattern. Then it will turn round and without corners. Of course, the choice of material for the ball is also of great importance. It must be intact.
Of course, there are people who can rely on their eye and make a spherical product by mathematical calculations. But will the right ball be obtained? Consider how you can make it to the exact size.
How to make a balloon pattern?
The easiest way to make a ball with a diameter of not more than one meter. If the size is larger, some inconvenience may arise.
Usually the ball is made from petals of the same size and shape. They are glued together or sewn together on a drawn line. At the same time, you should not forget to leave allowances for seams.
If you make a ball made of foam rubber, you can make not separate petals, but linked. That is, you do not need to make each petal separately, but draw the required shape immediately on the foam rubber. In this case, there is no need to leave allowances for the seam. But this is only suitable for foam rubber.
Beginning of work
To get the correct pattern of the ball, you must know its diameter, that is, the apparent value.
Next we need to decide how many petals the ball will consist of. A small one can consist of six. The larger the ball and its circumference, the more petals will be required.
To determine the height of the petal, you need to divide the circumference into two.
To calculate the circumference of a ball, its diameter must be multiplied by a constant value of π = 3.14.
Accordingly, if the diameter of the ball is thirty centimeters, the circumference is 30 * 3.14 = 94.2. The height of the petal will be 94.2 / 2 = 47.1 cm.
Next, you can calculate the width of the petal. If we want to have eight, then the length of the circle 94.2 divide by 8, we get 11.775 cm.
Afterword
If for some reason all these calculations are complex, then you can search for a special calculation generator to get the correct pattern of the ball. Just enter the desired diameter and number of petals, and the program itself generates the size of the future ball (even with allowance for seams).
