Sewing Operation:
Sewing is the most important operation in the process of garments making or other similar product. Sewing means joining of different parts of garments with the use of needle and thread. Without needle and thread, we can also make garments by using alternative methods of joining like adhesive, welding etc. Generally there are two things involved in sewing process, i. e. stitches and seams. Sewing is the most important among all the processes of garments joining. The main purpose of sewing is to produce seam.

The joining process “sewing” can be characterized on the basis of information about the sewing thread, the textile fabric, and the construction of the connection (thread/laying of textile fabric). A connection by sewing occurs by the linking or chaining of one or more sewing threads with the textile fabric. The manner, position, and number of linking or interlacing points in the textile fabric describe the joint produced.
Sewing can be defined as the craft of fastening or attaching objects using stitches made with a needle and thread. It is a term used to describe the process used in factories to mass-produce a wide range of garments and other goods that are created by joining different components together along the course of a structured process. Sewing is done by putting parts together and joining into a whole garment. The basic sewing parameters include:
Stitches,
Seams,
A method of sewing.

Seam:
Seam is a line where two pieces of fabric are sewn together in a garment or other articles. A seam is basically a line of stitching. Seams are stitched on the seam line. The seam allowance is the distance between the seam line and the cut edge. The standard seam allowance is (1.5 cm) wide.
Stitch:
Loop or loops of one or more threads when bounds with each other, either by interlacing, interloping, interloping or combination of those when sewing fabric, each unit of such configuration is called stitch.
