Types of seams. According to their main function

Today I publish an article whose authorship is not mine but of a very good colleague. Belu Chi she wanted to share her knowledge with us by writing this interesting article on the types of sewing classified by its main function. Belu is also the author of ABCSEAMS

Have you ever asked yourself why we people tend to classify everything?

I’ve just read an article about a neurological study that says when we classify something, what we really do is analyze it to understand it. We people classify things by common elements and make groups, then we know.
That is how our brain works. For instance: if you go to a supermarket to buy some apples, what is the first thing you look for?… yep!, veggies and fruits. We instinctively make a simple logical classification of the food in a supermarket by a common element, in this case: the nature of their composition.

“Being familiar with seams types is crucial to getting the best result”

1. Construction Seams
2. Hems and Finishes
3. Details
