 Fiber is the smallest unit of a textile. Cellulosic fiber is made of plant material, whereas protein fiber is made from animals. In contrast, synthetic fiber is made of material produced by chemical and mechanical processes. When you twist the fiber, you interlock the material together and form a yarn. You need to use spinning machines for the mass production of yarn.
 Thread is a type of yarn. Weaving is a method of interlocking vertical and horizontal threads. The vertical threads are the warp, and the horizontal threads are the weft. Weaving turns the one-dimensional piece of thread into a two-dimensional piece of cloth.
 Cloth is a type of fabric that is a thin, flexible material. Textile is an umbrella term that includes fibers, yarns, and threads. Textile also includes different fabric types. Felt is a nonwoven fabric, a textile material produced by matting, condensing, and pressing animal fibers together.

 A principle is a foundation for behaviors. A community comprises a variety of groups with shared principles. The community becomes a society when its members pressure one another to behave in a certain way.
- Principle; that means, the foundation for behaviors.
- Community; that means, a variety of groups with shared principles.
- Society; that means, an ordered community.
 A fabric sheet is good in clothing when it does not wear and tear too fast. Likewise, a community is good when it does not lose many members as time passes. How well members interact among themselves is like how well the woven threads hold together in the clothing fabric. All of this gives rise to the metaphor of social fabric. In the metaphor, community members are the threads.
 Each thread is a member of the fabric “community.” How tight the threads are to one another in the weave determines how good the fabric is. In the metaphor, people consider the social interaction the weave.
 The social fabric comprises members woven together through social interaction. The more they have positive interactions, the tighter the community is built. Textile workers use better weaves to strengthen the fabric. Likewise, members generate more positive interactions to strengthen their human community.
