Knitting & Weaving
There are different ways to produce fabric. Two main ways are knitting and weaving.
There are many different ways to weave like, the plain weave. The plain weave is the simplest weave in which the cross-wise yarn is passed over then under the length-wise yarn. There is the Twill weave in which the weft yarn is passed over and under either 1-3 warp yarns & beginning one warp yarn back on each new row. Satin weave produces a smooth, shiny-surfaced fabric that you get from passing the weft yarn over and under a few warp yarns. There are many more types of weaving.
Knitting is when you make fabric by looping yarn together. A gauge in knitting is how many loops you have per inch in a fabric. Just like weaving there are numerous types of knitting. There are weft knits which are knits made with only one yarn that runs cross-wise making horizontal rows of connected loops. Warp knits are made with several yarns that loop length-wise.
Other ways to produce fabric
If you don't want to weave or knit a fabric you can also use these methods:
Non-woven are fabrics put together using heat, chemicals, friction and pressure.
Laces/Nets are made by knotting, twisting or looping the yarns.
Braided fabrics are created by interlacing three or more yarns to create a diagonal pattern downwards.
Bonded fabrics are made by permanently putting together two layers by lamination.
