The term cut and sew is a manufacturing process used in the making of custom garments within the fashion industry.
[3] In a way, this manufacturing process is a more efficient way of making clothing as opposed to weaving, sewing, crocheting and knitting by hand, since it is machine operated.
Material like leather used to require special thread and thicker needles as well as a sharper tool to cut it which now can be done through this process with such advanced machines.
The cut and sew manufacturing process is essential to apparel because it allows people to have more control over designs/patterns and allows them to be as creative as can be due to its flexibility.
The process of working with a cut and sew factory would start with sending them a tech pack and/or providing a sew-by sample.
