For you beginners or even if you are slightly more skilled, you are buying patterns and occasionally you see barbarians names like fusible interfacing piece etc ..., well, you say what's this thing? is it  done to annoy me when I started? It's already hard enough understanding between the pattern and the handling of the sewing machine!
I'll try to give you some answers .....

The interfacing (fusible or not) is a substance used to enhance a piece of clothing to make the assembly easier or to give it rigidity and held for the proper fit of the garment.
Is it necessary?

Yes, to make it look "finished". In each type of clothing, there will be one or more parts to interface: collar and cuffs of a blouse, front, collar, the hight of the sleeves of a jacket, etc ....

There are several kinds, what do I choose?

This is where it gets difficult for several reasons:
-> It is necessary to know the material of the fabric you want interface because it determines the choice,
-> You have to know interfacings to know which one to choose.
-> You need to find the right place where you can find a selection of interfacings for sale with someone who can guide you in your choice
in other words the squared circle!

To help you, there are two major types of interfacing: the "to be sewn" and the "fusible".

The "to be sewn" interfacings are traditional, still used by tailors or when we have a fabric that does not support fusible temperature.
There are several thickness, your choice will be an interfacing of the same thickness or slightly less than the fabric you need to improve.

Assembly is done by cutting the covering to the same part to interface and building the two layers together. assembly is done as if it was only a single layer.

The traditional assembly is more sophisticated  and is called "frosting" see free documents "method for mounting the suit canvas."

Fusible interfacings are faster to put in place but more delicate implementation because the sticking must be perfect to be invisible. This implies that we used the correct method of collage and especially that the fusible interfacing is of good quality.

How to recognize a good quality interfacing?

Visually, there is a very simple way, the adhesive must be placed by dots, drop out cotton cloth with a layer of smooth and glossy glue, the collage will not be sustainable not efficient or will show blisters.

Anyway, it is imperative to make a sticking test on your fabric before you start. Because a failure on front clothing, all blistered or too stiff, can be really ugly!
