What Are Nahttypen (Seam Types)?

Indicatively, light weight clothes can have dainty seams, whereas heavy denim can have robust seams.
The knowledge of the types of seams will enable you to select the best method to use in your sewing work.
The relevance of the Seam Type in Sewing.
Most of the beginners believe that all sewing involves is holding a piece of fabric and stitching it up but those who have really been sewing know that a piece of sewing can be the difference between success and failure.
The following are some of the reasons why the type of seam is important:
1. Durability
Some seams are heavier and are intended to be used in garments which are subjected to stress like a pair of jeans or a sporting suit.
2. Comfort
Other seams are more smooth and less bulky hence perfect to make use of in clothes that are worn close to the skin.
3. Appearance
Professional-style clothes usually rely on the clean and finished seams.
4. Fabric Protection
Finishes on seams help to stop the fabric fraying out and also increase the life of the fabric.
