For many purposes, a serger machine is therefore much more useful than your average sewing machine. Now, a serger machine has the ability to perform many different types of stitches.
One of the most basic yet useful stitch types that a serger machine can create is known as the flatlock. Today, we are going to discuss exactly what a flatlock seam is, how it is made, and how to perform this task using a serger machine.
What is a Flatlock and What is it Used For?
Before we can get to talking about how to make a flatlock stitch with your serger machine, you first need to know exactly what it is. So, there are many different types of stitches that a serger machine can create, with one of the most useful ones being the flatlock stitch. This is a special type of stitch that be made using either two threads or threads.
As the name of it implies, the point of a flatlock it is to create a very flat seam that is perfectly flat on both sides. A flatlock stitch has a variety of purposes, with the biggest advantage of it being that it doesn’t have much bulk, because the edges of the fabric are totally encased in the looper threads and the stitching.
If you are looking to perform some hemming, or create some items that are ready to wear, then it is a fantastic stitch to use. If you are making fitted items, such as sportswear, that need to be very tight and form fitting, then it is also a great stitch to use. Moreover, it can also be great in terms of decorative purposes.
The Two Sides of the Flatlock Stitch
What is important to note about the flatlock stitch on a serger machine is that there is technically a wrong side and a right side. That being said, the right side of the flatlock stitch generally has the appearance of small rows of bars that looks like a small ladder.
The other side, which is generally known as the wrong side, is going to show the looper threads as they snake across the division of the fabric.
This is sometimes known as the loop side. Depending on the project you are doing, both looks can be ideal. If you are looking to create the look of a blind hem, then the right side of the stitch can be ideal. However, if you are looking for a more decorative appearance, then the wrong side of the stitch may be desirable.
