I want to learn more about how a tee shirt is made.

I’m happy to help! A tee shirt is a garment that is made by weaving two or more yarns together, usually cotton, nylon, and/or polyester. The weave of the fabric is called a “yarn” and each row of the weave is called a “course”. Each course has a certain number of threads in it, depending on the type of fabric you are making. For example, a plain weave fabric will have one thread in each course, while a twill weave fabric will have two threads in each course.
