If you want to learn to sew a straight line, you will have to practice a little bit, preferably not on your first masterpiece, but on an unnecessary fabric scrap.

As in its hand variant, plain seam is used to join one part of a garment with another. In order to make a plain seam, get two parts of a garment together with right sides facing. The stitch is made on the wrong side of fabric. Two parts may be beforehand joined with a tacking stitch, if necessary. Stitch line width and stitch length depend on a type of fabric. Very thin tissues, for example, chiffon or crêpe de Chine, are recommended to be stitched with a piece of thin paper in order to avoid fabric stretching.
Strop seam may be used for joining parts of a garment, as well as for trimming.
Step 1.To make such seam you need to join two parts of a garment with right sides facing; if you want to hide ends of a garment, then one part must be strop seam width + 1/3” longer than another.
Step 2.Next we stitch our parts with a plain seam. Lower part juts out; a stitch line goes ¼” from the edge of the upper part. Press the seam to the side with a smaller edge.

Make a stitch line 1/3” from the folded seam.
Linen seam is used when making linen and clothes without lining. Linen seam is made in the following way: two parts are tacked together so that the lower one is ¼” longer. Stitch these parts, remove tacking and press seams wrapping the smaller edge in the bigger one. Make a neat stitch line 1/10” from the fold edge.

You may also hide fabric cut inside the seam fold fabric first at ¼” and then do it once more on a necessary width, so that the cut appears inside the seam, and make a stitch line.

Decorative seams are very often used for decorating garments. They should be made on the right side of a garment. Many sewing machines have different kinds of decorative seams.
