What is the theme, structure and organizational form of the model?

1. Single pattern: it is an independent individual with integrity and the most basic unit that constitutes a suitable pattern and a continuous pattern. The composition forms of individual patterns can be divided into two categories: symmetry and balance.

2, suitable for patterns: limited by a certain shape, patterns must be placed in a specific shape. Even if the shape is removed, the pattern still maintains the characteristics of the outline, such as circle, square, triangle, ellipse, diamond and so on. It is also useful to use natural shapes as contours, such as gourd shape, flower shape, leaf shape, peach shape, fan shape and so on.

3. Corner pattern: refers to the pattern decorated in the corner of the body, also known as corner flower. There are right angles, obtuse angles and acute angles. Corner patterns can be used alone or in combination with edge patterns. There are two kinds of corner patterns: symmetrical and balanced. Corner patterns are widely used, such as pillowcases, sheets, tablecloths, carpets, scarves and other compositions, and corner patterns are often used.

4. Edge pattern: It is the pattern around the decorative form. It is generally used to set off the central pattern or match the corner pattern, and can also be used to decorate the edge of the car body independently. The difference between the edge pattern and the double-sided continuous pattern is that the double-sided continuous pattern can extend indefinitely, while the edge pattern is limited by the shape.

5. Continuous pattern: it is a pattern that moves up and down or left and right repeatedly with one or several basic unit patterns, and can also be extended repeatedly in four directions. Its characteristic is continuity.
