Step-By-Step Guide - French Seam

This post is for those who just discovered my sewing patterns or have recently decided to dive into the sewing world and - at some point, are wondering: how could I nicely finish the seam allowances without the overlock (serger) machine?!
Who has already seen my sewing instructions knows that I love making French seams. This seam finishing is ideal if you are working with sheer or lightweight fabrics. It might seem hard to execute, but to me, it is the easiest and the faster to make; if you want your garment to look professionally made, you need to practice.
So, I'm going to show you how to make a French seam, once again.
You will need a regular sewing machine, scissors, pins, ruler, iron with ironing board, and two fabric scraps (20x20 cm) for the tutorial.

Usually, for the French seam, the seam allowance should be 1,5 cm. All my sewing patterns already include it, and there's no need to add anything.
So let's start:

Pin your fabric wrong sides together, as shown below.

Then trim the seam allowance down to 4 mm.

Now, press the seam allowance to one side, as shown below. Press on both sides of the fabric till the seam lays completely flat.

Then fold the fabric on the seam, so the right sides facing together, and press again till the seam lays flat. Pin the fabric so it won't move while stitching.

Make the second stitch, again at 7 mm or 1/4" from the edge (or line up the edge of the fabric to the right side of the presser foot as you can see below). 

As specified above, the full seam allowance amount is 1,5 cm, so when you make the French seam, you stitch twice at 7 mm from the edge.

Finally, press the French seam to one side, on both sides of the fabric, so it lays completely flat.

I hope you'll find the above useful. If you have any suggestions, let me know, or leave a comment down here.
