a process in which two types of thread or yarn are interlaced together the two types of threads run in different directions, with the warp threads running length-wise as the weft threads get inserted horizontally. In weaving threads are always straight and perpendicular to each other. The most common means of producing woven textiles is on a machine called the loom, which can be configured to produce both flat sheets as well as circular structures.
unlike weaving knitting typically uses a single source of yarn that loops onto itself, over and under the established path. This gives knitted fabrics greater flexibility. It also allows for a greater contour control.
chrochet is a method, similar to knitting, that manipulates loops of yarn with typically one active loop the chrochet doesn't lend itself to unraveling during the production process. There do not seem to be active DIY chrochet projects, it's a method that remains confined to a craft domain with very little automation. Mainly because unlike knitting the process entails multiple loops on one needle rather than multiple stitches on multiple needles as seen in the knitting machines.
