Features Required In the Best Serger

Before we divulge the features present in the Elna 664 Pro, let us understand what a general serger should have. These features will help you compare between the Elna 664 Pro and any other serger in the market. Furthermore, you can determine if the Elna 664 pro contains these features.

If you are a beginner seamstress, then it will help you realize the necessary features that need to be present in the serger. It will also guide you in any future purchases you make regarding the Elna 664 Pro or other serger models. Check out the features required in the best serger.

Rolled Hem

A machine with a rolled hem built-in will not need you to change the presser foot and needle plate frequently. If the serger does not have one, then you will need to change them before every stitch. This can be time-consuming and a huge hassle, especially for people using a serger for the first time.
The changing process also takes up a lot of time. That is why it is better to look for a machine with a built-in switch for a rolled hem. However, if you will not be doing rolled hem frequently, you might not require this switch. In that scenario, you can go for a model that does not have rolled hem switch.

Cutting Blades

The next feature that you should look for is built-in cutting blades. You can use these blades for cutting the edge when you are sewing. Due to the presence of built-in cutting blades, you will not need extra blades for cutting the thread. These cutting blades save a lot of time and effort on your part.

While using cutting blades, you need to be very cautious since they are delicate. If they run over a pin or any other hard surface, they can get damaged. The damaged cutting blade will not work effectively. Therefore, you will need to change the cutting blades so that you can resume their proper usage again.

Threading System

Beginners are often confused about the serger’s threading system. Depending on the model, the serger can feature 2/3/4/8 thread systems. The 4 system is perfect for beginners, while experts always use the 8 system. However, if you are sure that you can learn the usage easily, then even a beginner can go for any of these thread systems.

Another thing to remember while checking the threading system is the ease of threading. If it is difficult to thread the Elna 664 pro serger, it will be time-consuming no matter what the thread system is. Several modern models come with easy threading features. This feature makes it easy for beginners as well to thread the machine.

Differential Feed

Every serger has two feed dogs set, located underneath the presser foot. These feed dogs are responsible for moving the fabric through the serger. In this, the differential feed helps in controlling both the feed dogs’ movements. The differential feed in your serger is a very important element.

When buying a serger, you need to check if the differential feed is adjustable. Having an adjustable differential feed will ensure that you can sew stretchable fabrics with them getting stretched. Generally, 2 to 1 is the right differential feed for any serger model. However, some models may have different adjustability options.

Free Arm

The free arm in the machine is a feature that you may not find in many high-quality sergers. If you have experience using a serger, this feature will not hold much importance. However, for beginners, this feature can help a lot out. It makes using the serger much easier. The free arm feature provides you with extra space for sewing sleeves or cuffs.

Experts in handling sergers and have stitched using them for a long time will not need a free arm. They can make proper stitches even without that extra space. But if you are new to using a serger, then the free arm feature will help you make clean stitches. This is also necessary since it is hard to stitch areas like cuffs and sleeves.


The price of the serger is an important criterion. Most people have a fixed budget within which they wish to buy the machine. Depending on what your sewing usage will be, the price of the machine will vary. If you are looking for a serger for small stitching works, then a low-budget serger would do the job.

Some people, however, need a machine for more professional jobs. If this is the case with you, it is better to opt for high-end machines. These machines may fall on the higher price spectrum, but they will contain some of the best and necessary features. Your budget and the serger’s price will play an essential role when choosing a serger for yourself.

Features of the Elna 664 Pro Serger

Now that you know what features need to be present in a good-quality serger let us check out the features of the Elna 664 Pro. As already mentioned, the Elna 664 Pro has some amazing and unique features that make it quite a favorable choice. Despite so many useful and amazing features, using the machine is not hard at all.

Knowing the features present in this model and comparing them with the section ahead, you can decide if this is the model for you. One thing to remember is that the Elna 664 Pro is a good choice for both amateurs and experts. However, you cannot confirm this without knowing the functionalities of the machine.

Manual and Intuitive Threading System

Threading a serger is a very hard task, especially if you have never done it before. Many professionals still find it time-consuming to thread a serger. However, the Elna 664 Pro serger has made threading quite an easy task. While threading this machine, you will not have to work out your brains.

The slower lopper of the serger is self-threading, and it has a color-coded system. While sewing, the serger’s tilting clamp locks its position. However, while threading, you can move the tilting clamp forward very easily. The machine also has a program reference panel that you will find on its right side.

The panel contains information about the correct tension settings required for different types of stitching. This helps in saving an immense time since you will not need to serge-test the seams. It proves to be a great help when you thread the serger. In case you need assistance with the tension settings, you can consult the reference panel.

2/3/4 Thread System

In the earlier section, we had discussed the threading system present in a serger. Generally, sergers have a 2/3/4/8 system, and the Elna 664 pro has a 2/3/4 thread system. This model can sew all these spools at once, which makes the machine quite versatile. Moreover, it can create around one dozen stitches.

Some examples of stitches produced by the serger are 2/3-thread flatlock, 3-thread overlock, 3-thread narrow hem, 4-thread gathering stitch, and 2-thread overcast. It can also produce 2/3-thread rolled hem, 3-thread wide stitch, 4-thread safety overlock, stretch wrap and stretch knit. The reference guide helps in selecting the stitching type easily.

A great feature it has is the in-build cutting blade that we discussed in the earlier section. This blade helps in trimming the extra fabric while sewing. You can adjust the cutting width between 3.0 and 7.0 mm depending on the fabric’s overcasting requirements. Furthermore, you can adjust the length between 1.0 and 5.0 mm.

Adjustable Differential Feed and Adjustable Foot Pressure

We have already mentioned the importance of the differential feed in the previous section. Moreover, the adjustability of the differential feed will create an impact on the sewing results. The Elna 664 Pro comes with an adjustable differential feed which makes the stitching quality high.

You can set the adjustability between 0.5 and 2.25mm, which is quite good. With this adjustability range, you can work well with stretchable fabrics, sew ruffled edges, and work with knit. Moreover, the stretchable fabric will not get damaged when working with such an adjustable differential feed.

Another feature is the adjustable foot pressure which maintains the speed of the stitching. You can choose a pace according to your comfort. Depending on the fabric that you are stitching, you can go fast or slow with the foot pressure. Both these features are completely under your control which is great.

Accessory Box

The cost of Elna 664 pro serger is slightly more than other sergers with a ¾ threading system. Some of these sergers are from Singer, Brother, and Janome, which are also quite well-known. However, the difference in the serger’s pricing is due to Elna’s presence of a fully-equipped accessory box.

The box has some amazing tools and attachments that you might not find in other brands. You will need to buy some of the tools individually; however, in this model, you do not. The box contains the 7 snap-on feet and a cover used to protect the machine from dust.

Some other accessories like the nets, needles, 2-thread converter, cleaning brush, and spool holder cap is present in the box. You can also find tweezers, screwdrivers, one wrench, tension release clips, and lubricating oil. The serger’s front panel has a storage compartment for keeping the accessory box.
