What are the important properties of seam?
However, the most important properties of a seam are strength, durability, elasticity, security, and good appearance.
Why is it important to sew seam accurately?
Sewing accurate seam allowances is an important key to having your pattern pieces fit together. When the seam allowance is not accurate, you are changing the intended outcome of the pattern.
What is the purpose of seam finish?
A seam finish is a treatment that secures and neatens the raw edges of a plain seam to prevent raveling, by sewing over the raw edges or enclosing them in some sort of binding. On mass-produced clothing, the seam allowances of plain seams are usually trimmed and stitched together with an overlock stitch using a serger.
What are seams in sewing?

What is the importance of drafting pattern?
Pattern Drafting is an important part of fashion designing and requires tremendous skills and practice. Pattern drafting is where pattern pieces are drawn on paper according to body measurement which becomes the base for designers to create garments.
What does inside seam line mean?
Take a look at the image below: The outer-most edge of the sewing pattern represents the edge of the fabric, while the inner line, marked at a specified distance in, depicts the seamline or (stitch-line). This distance defines the seam allowance.
Why is it important to notch a seam?
Cutting the notch outwards creates an outward triangular fabric extension and is better for sewing beginners as it leaves less room for error such as accidentally cutting too far into the seam allowance (too close to the seam line).
Why is it important to carefully select the seams and seam finishes?
seams and seam finishes are important—even critical—steps in the construc- tion process. They are basic techniques used in the sewing process. … A seam finish is applied to/used on the unfinished seam edge to prevent raveling, curling, or rolling.
What is seam in fashion?

Why are seams clipped?
When sewing a curved seam, you are supposed to be clipping or notching the seam allowance, so that the seam can stay flat and smooth. The rule is that when the seam is concave, you clip the seam allowance; when the seam is convex, you notch the seam allowance. This is an important step.
What is the purpose of Understitching?
An understitch is sewn along the edge of the lining or facing nearest the armhole or neckline and works to secure the lining or facing to the seam allowances which in turn keeps everything neatly tucked inside the garment instead of poking out and being visible from the right side.
Where are notches used?
Notches are commonly used in material impact tests where a morphological break of a controlled origin is necessary to achieve standardized characterization of fracture resistance of the material. The most common is the Charpy impact test, which uses a pendulum hammer (striker) to strike a horizontal notched specimen.
What is the difference between notching and snipping?
Notching is similar to clipping, but instead of taking a single snip out of the fabric, you cut out a small amount of fabric. Notching is used on convex curves and exterior corners because the seam allowance is larger than the space it will be turned into.
How do you notch a seam?
To notch your convex seam, snip little triangles out of the seam allowance every 1/2″ or so. Get nice and close to your stitches, without snipping right through them of course. Turn your seam out to the right side, give it a good press and revel in that lovely un-bunchy flatness!
What is the difference between notching and clipping?
Unlike clipping, which allows fabric to spread out, notching enables it to come closer together without the bulk, by removing the excess fabric.
