All non-knitted fabrics of fabric materials have a standard weaving structure - base and weft. What does this mean? Imagine a long path of material in a roll. Those threads that are laid along its length are called warp threads. And those that go across are weft threads (emphasis on A). Depending on the direction of the threads, a cut of the parts is built when sewing garments, the characteristics of planting and joining are taken into account. These are those basic fundamental points, without which it is simply impossible to sew a high-quality product.
What does the longitudinal edge indicate - the edge of the fabric?
In fact, the purpose of this edging is of interest to beginner seamstresses. So, the longitudinal edge (edge) of the fabric indicates to us the direction of the shared thread. The edge does not spread, it is fixed in a special textile way and prevents threads and fibers from breaking up along the roll. If a piece of fabric lies in front of you and you don’t know how to determine its shared thread, just lay out the patterns along the edge, strictly parallel to it!
Another, more professional method of determining the shared thread is an attempt to stretch the fabric. All non-knitted fabrics stretch slightly against the equity and are absolutely inelastic on it. That is, if you have a piece of material with a removed edge, then you need to try to stretch it. Exactly where it stretches, there will be a weft thread, and where it is static, there will be a shared thread. Note that the oblique fabric stretches the most, but then some deformation will be noticeable.

What is the longitudinal edge of the fabric for? Perhaps few readers have ever wondered for what purpose on the uniform weaving of fabric it is the edge that differs in a special kind of weaving and is clearly different from the main texture. As already mentioned, the edge of the fabric prevents the roll from shedding around the edges. This is the first and leading edge feature.
The second, no less important point is the definition of shared. We give an example of an imbalance in the balance of the shared cut.
The beginning seamstress cut a sleeve against a shared thread. Everything went according to plan, the pattern was built with precision, the connection was completed without any violations, I tried very hard. But the fitting turned out to be tight at the fitting. It was impossible to raise a hand, it pulled and squeezed in the area of the forearm, and everything gathered in wrinkles in the area of the armpit. The young craftswoman fell into despair, and was right - it was already impossible to save the sleeve. All because of the fact that along the lobar tissue does not stretch at all, and the student made the width of the sleeve along the lobar and thereby pulled the forearm of the client.
Importance in cutting
Of course, the longitudinal edge-edge of the fabric determines the layout of the patterns and the consumption of fabric. Sometimes it seems that the material would have gone much less if it were laid out in a chaotic direction or across the edge. But, as we wrote above, such deviations from the rules are obviously doomed to failure.
Every beginning seamstress knows from the first lessons that the longitudinal edge (the edge of the fabric is the name according to the terminology of sewing disciplines) is a clear and categorical reference point for the direction of cut and a characteristic for calculating the consumption of material on the product.
