Lesson 46-50 (5) : Various Seams and its Purposes

Objectives

At the end of this lesson you shall be able to
• know about various classes of seams
• produce the seams on fabric by sewing machines
• know the formation & construction process of various seams
• use different seams as per the requirement of the garment.

A seam is the join where two or more layers of fabric or other materials are held together with stitches.
In garment construction, seams are classified by their type (plain, lapped, bound, flat) and position in the finished
garment (center back seam, inseam, side seam). Seams are finished with a variety of techniques to prevent
raveling of raw fabric edges and to neaten the inside of garments.
It is important to be familiar with various seam types, their applications and variations available so that you can
choose the right seam to suit your sewing needs.
Seam Classification
Seams are classified according to the type/number of components used. There are six basic types of seam
classes which are explained below with their descriptions:
Seam Classes
Class 1 - Superimposed seam
Class 2 - Lapped seam

Class 3 - Bound seams
Class 4 - Flat seams
Class 5 - Decorative/Ornamental stitching
Class 6 - Edge finishing/neatening

Class 1 - Superimposed seam(s)
The seam of class-1 is called superimposed seam. This is the most common & mostly used seam for joining
fabrics. In this seam, two plies of fabric are placed on one another perfectly & then the fabrics are sewn. The sewn
edges of the fabrics remain in the same side. There are various types of seams within this class.
