(1) The characteristics of the organizational form of the decorative patterns of luggage. From the perspective of the organizational form of decorative patterns of luggage, there are separate, continuous, and group types, which are expressed as separate patterns, suitable patterns, two-sided continuous, four-sided continuous, and unique. Type integrated patterns, etc., and each form has distinct characteristics.

The individual patterns are eye-catching, prominent, and lively, and often become the focus of vision in the shape of the luggage such as best travel backpack; the two-sided continuous, banded group and border are mainly "linear" performance, often outlined, divided and defined in the shape of the luggage Function: The tetragonal continuous, faceted group appears in the form of enveloping faces. In pattern decoration, all symmetrical patterns and all continuous patterns are concrete manifestations of the repeated form. The left-right symmetry and up-down symmetry of a single pattern are the repetitions of the same image; the symmetry suitable for radiation, centripetal, and rotational conversion in the pattern is the repetition of the unit structure, and these different repetitions each form an orderly unity of change.

(2) The spatial state of the decorative pattern of the luggage
The pattern decoration of luggage can be divided into two categories: plane pattern and three-dimensional pattern. Graphic patterns are mostly used to express the intent of graphic decoration design, such as fabric pattern design, patchwork pattern design, dyeing and weaving pattern design, etc. The three-dimensional pattern is relative to the flat pattern, and refers to the decorative pattern design with visual and tactile sense of three-dimensional. In the luggage pattern design, the flat pattern refers to the luggage pattern without thickness. The designer makes the pattern close to the surface of hot topic bags material through printing, dyeing, painting and other technological means, or directly uses the fabric texture to integrate the pattern and color into the material.

Two-sided continuous and four-sided continuous are three-dimensional decorative patterns of luggage with a certain thickness, which are adorned on the surface of the package body, or the luggage fabric forms a decorative pattern effect of varying thickness and unevenness in the process of making and weaving. The three-dimensional pattern is attached to the surface of the luggage in a three-dimensional form, which emphasizes a sense of volume, weight and space, and enhances the visual appeal of the luggage image. The bag design shown in Figure 6-44, the decoration made by the bow has a certain three-dimensional feature.The big backpacks can also use.

(3) Permutation and combination of luggage pattern modeling
In decorative composition, another shape is often created based on the contour edge of a certain shape, so that the shape and the shape are adapted to each other, and the image can be fully expressed through mutual contrast. The form is mutually misplaced and self-adjusted, the space can be used rationally, the form is compact and complete, and the natural order is freely presented. Effectively shows the adaptive relationship between form and form.

① The mutual borrowing of shape and the contour line: The mutual borrowing of the shape and the contour line shows that a common contour line is formed. The public contour line makes the two shapes restricted and interdependent, resulting in a symbiosis phenomenon, enhancing the expressive power of decorative art, creating a unique art form through basic decorative modeling and composition, resulting in a tight combination of form and form Improve the utilization of space and reflect the clever composition of the picture, as shown in Figure 6-45.

②The superposition of shape and shape: The superposition of shape and shape can produce a clear front-to-back relationship; the complete form is in the front, and the obscured incomplete form is in the back. When the shape of the front side appears as the main body, the main black and white changes are usually applied to the former, while the latter is relatively weakened. The form with strong personality is often arranged in the front, and the form at the back is relatively concise, which will effectively set off the form at the front. As shown in Figure 6-46.
