Mathematics is described as the “science of pattern”. Any sequence of numbers that can be modeled by a mathematical function is considered a pattern. |

### ✂ Patterns

- Patterns are repeated in a predictable manner. They can be a template or model that can be used to generate objects or parts of them.
- Mathematics has tried to describe the world in terms of patterns. The aim is to expose the world in a simple way.
- In sewing, patterns are used to create a garment. Depending on whether it is a personalized model (whose pattern will be made with the measurements of the person or object to which it is dedicated), or standard clothing (whose patterns will be designed to serve an indefinite number of times, adapting them to conventional sizes) and be able to do as many times as we want. In this way, it will be easier to create many things or equal garments.

- Tailors and seamstresses use mathematics continuously to make a pattern and use it to create similar clothes, calculating and modifying the values depending on the personalized measure.

- Thus, with a standard pattern you can change the scale by increasing or decreasing it according to a person’s size.

In the elaboration of clothes we use simple mathematics. They are simple but necessary knowledge in the taking of measurements, the drawing of molds and in the cut in the fabric. In Cotiana life, the use of patterns is very common, and is reflected throughout the field of design, whether furniture, accessories, decoration of fabrics, …

Anyone who wants to learn how to make clothes, create designs, whether working with carvings, molds already made or taking measurements and making molds, must know them in order to understand the theory or to apply fashion developments or buy fabrics.

In more than 90% of the countries of the world the system to measure is the Metric System and the measure used in this system is the Metro.

(There are only 3 countries in the world where the metric system is not used: Liberia, Myanmar and the United States that use the Anglo-Saxon system and whose measurement used is ** inch) **

** **📏

*Tape measure:*

We know that a metre is 100 centimetres long. Each centimeter has 10 millimeters. One centimetre can clearly see 10 stripes. The half of a centimetre is marked with the longest line.

*✂ Lines, geometric figures and fractions most used in the drawing of molds or patterns of clothing: *

** ** Half of a total measurement: divide the total measurement by 2 using the simple calculator . One third of the measurement total or one third: Divide the measurement total by 3 using the simple calculator

One quarter of the measurement total: Divide the measurement total by 4 using the simple calculator . Geometry : Geometry must know how to draw different lines and geometric shapes like:

### 📐 * Symmetry. .*

Calculate measurements to make patterns:

Calculate measurements to make patterns:

- Anything is symmetrical when the right side is equal to the left, as is often the case with humans, animals, and some geometric figures.
- Our body on the right side is equal to the left side. We have two arms, one right and one left, two legs, one right and one left, and so on.
- In order to trace patterns, we make molds with 1/4 of the body contour measurement, since we are symmetrical. When you open the mold halfway, it fits perfectly in our front or back. From there the basic moulds of skirt and blouse, trousers, dress, sleeve, neck etc. are traced using the techniques of symmetry.
- When the mould is traced with the measurements of
**1/4 on a double paper**, and that fold of the paper remains in the centre of the mould, when we cut it we find that it is symmetrical and that it is not necessary to rectify the right and left measurements because, by simple logic, this right mould is an exact copy of the left side.

👗 * SIMPLE EXAMPLES TO MAKE THE PATTERN OF A DRESS: *

** DOLL TILDA. PATTERNS AND DRESSES. **

The Tilda dolls were created by the Norwegian designer ** Tone Finnange. **

- Their enormous success is based on their sale together with the patterns to create them. Also, they differ from the rest because of their nice and peculiar structure. We can find many patterns of the doll and her dresses, as it is a very gratifying task due to its simplicity and appearance.
- These are cloth dolls, with long showers and small heads, which can be flexible and decorate any corner, and can adopt any feminine, masculine form, since their patterns are, in reality, lacking in gender forms.

- In its design are used light colors, discreet with small brown features, in the hair and eyes. Their clothing is very varied, and we can find many models and patterns on the net.
- The different parts are easily created and sewn, even by the least expert in the world of needle and thread. The darning is hidden with invisible stitching and the material of choice is fabric. We proceed to give the desired volume with a cotton filling. However, they are usually quite elongated and flattened.

To begin with, a drawing is created on paper, which is then cut into the fabric following the pattern, so that the different parts can be sewn together. Finally, they are filled with wadding, with special care to leave little material in the part of the seams, since otherwise they could not be articulated.

** ✍ Didactic applications: **

- Calculate measurements. Increase and decrease with grids.
- Use tape measure, ruler, square and bevel.
- Make patterns.
- Practice basic sewing.
- Recreate everyday or project scenes.
- Set up scenes of characters from various stories and texts.
- Collaborate with families.
- Use recycled materials (fabrics, foams, threads, wools,…)
- Take advantage of basic patterns to work on the design of clothes.
- Analyze anatomical proportions.
- Reflect symmetry in compositions. Ways to achieve it through folding, folding and symmetry axis.

** Project Traveller Pepa **

In our class.

** The Sixth Level ** we participate in the collaborative project, at national level, Traveller Pepa, being our school the representative center of Andalusia that welcomes it.

Publication in the blog of the Project |

In addition to collaborating in the suggested activities, we also make patterns for Pepa’s wardrobe.

In the images you can see the flamenco costume we made for her, and another for the I Jornadas de Palabras Azules, in which she was an exceptional guest.
