Amy has been getting lots of questions about when different serger stitches should be used, so she came up with this handy guide for us!
Different serging stitches and how to use them
When you’re learning to use a serger and finding out about all of the different stitches it can do, you might be wondering how to choose the right stitch for your project. Select a stitch that matches the needs of your project or garment (strength, stretch, edge finishing, etc). Many crafters use their sergers merely for finishing the raw edges of their sewing projects, but there’s so much more you can use it for when you know how the stitches work.
The 4-thread overlock is the most commonly used serger stitch. Take a look at the clothes you’re wearing. I’m sure this stitch makes an appearance somewhere! It’s a very durable and strong stitch and your best choice when seaming with your serger.
A 3-thread overlock is also a nice choice for seaming, but it’s not quite as strong as the 4-thread. This stitch uses only one needle, so you don’t have the extra durability of another needle thread in your seam as you do with the 4-thread overlock. You can still seam with it, but I wouldn’t use it on any area that will have a lot of stress put on it. It’s a fantastic choice for finishing the fabric edge on thick and medium weight woven and knit fabrics, and you can even make a blind hem with it.
If your machine has the ability to do 2-thread stitches, then you have the option to create an even flatter, thinner and lighter edge finish on your projects. A 2-thread overlock isn’t a good option for seaming, but it will give your project very lovely edges. This same stitch turns into the 2-thread flatlock, which is wonderful for piecing sportswear fabric and giving your garments the appearance of cover stitching. You should see how stretchy a 2-thread wrapped stitch can be!
My favorite stitch is a rolled hem. It is beautiful when you use decorative threads and hem sheer fabrics with it. The 2-thread variation of this stitch is perfect when you don’t want to add weight to your garment hem, but a 3-thread rolled hem can appear fuller and more filled in when you use the right threads.
For most of the 3-thread and 2-thread stitches, you have another variable — which needle do you use? When deciding whether to use the left or right needle, consider the thickness of your thread and also your fabric. The left needle should be used when you’re using thicker thread or sewing on thicker fabric. The right needle should be used when you’re serging on lightweight fabric or using a finer thread.
There are many more functions that each of these stitches can serve, and I haven’t even talked about all of your stitch choices! If you’d like to learn more about what your serger is capable of and how to choose what stitch to use, come on over and see me in my Beginner Serging class!
