Seams and Stiches
SEAMS AND STITCHES
Garments are shaped and formed in three ways:
• Materials moulded to form
• Fabric pieces cut to shape
• Pieces assembled together by stitching
The commonest way of assembling a garment is sewing garment parts together by SEAMS and STITCHES.
The standard guidelines for stitches and seams regarding nomenclature and types are provided by-
United States Federal Stitch and Seam Specifications (Federal Standard 751a) which was adopted in 1971 and revised in 1983
The British Standard Bs 3870: Schedule of stitching and seams was developed about the same time
Definition:
1. Stitch: A stitch is one unit of conformation of thread resulting from repeatedly passing a strand/strands or loop/loops of thread into or through a material at uniformly spaced intervals to form a series of stitches. Or
A stitch is one unit of conformation resulting from one or more strands or loops of thread intralooping, interlooping, or passing into or through a material.
Intralooping is passing of a loop of thread through another loop formed by the same thread.
Interlooping is the passing of a loop of thread through another loop formed by a different thread.
Interlacing, another term often used in stitches is passing of a thread over or around another thread or loop of another thread.
2. SEAM: A seam is a joint consisting of sequence of stitches uniting two or more pieces of material and is used for assembling parts in the production of sewn items. Or
The application of a series of stitches to hold several thickness of materials.
3. STITCHING: It consists of a sequence of stitches for finishing an edge or for ornamental purposes or both in preparing parts for assembling.

PROPERTIES OF SEAMS:
1. Appearance: A seam should be smooth, without turning or pucker, without missed or uneven stitches and no damage should
