Feed dogs with jagged metal strips are situated at the stitch plate under the presser foot when you feed the fabrics or garments into the sewing machine. As the fabric or garment is being sewn, the presser foot, needle plate, and feed dogs all move at the same time. It is possible to eliminate creases and stretched seams and lines by using a differential feed mechanism on certain other sergers or overlockers.

The moving knife in the sewing machine cuts or trims the seam allowance. The overcast stitch sewing machine’s tapestry needles and knives move in sync with the beat of the music.


These two loopers are used to create the stitch pattern instead of bobbins. The looper thread, on the other hand, does not go through the material. As the needle threads lock into place, the top and lower loopers are completed.

Stitch Your Fingers

One or two stitch fingers are being created by the serger stitches. The needle plate has little protrusions on it. Overlockers and sergers are particularly use for stitching seams, patterns, zippers, and other embellishments into textiles and other items. Sergers and ordinary sewing machines have many similarities, but there are significant differences, such as needles, threads, and bobbins.

When using an overcast stitch sewing machine, you’ll need to use more bobbins since it has more needles. Because sergers need many bobbins to accommodate the multiple threads linked to each sewing needle, they are more expensive.


A serger with more needles makes sewing and stitching simpler and quicker. You’ll save time compared to if you were to stitch by hand.


Using a serger or an overlocker, you may create more intricate motifs and patterns. You’ll just need to spend a fraction of the effort decorating unique stitches.

Lift the needle and the presser foot to turn an outer corner for continued sewing. Using the sewing finger, remove stitches from the cloth or garment by spinning it around. As soon as the presser foot has been lowered and the flywheel has been turned, the needle is ready to be inserted into the fabric or other substrate.

This kind of thread serger is best suited for medium to heavyweight materials or garments and textiles that are tailored. The fabric is stitched in two rows by two threads, with the looper threads wrapping in the edges as they sew.

5-Thread Serger

Tips When Using An Overcast Stitch Sewing Machine:

Beginners make up the majority of home sewers. To get the most out of a serger machine, here are a few pointers to keep in mind.

Clean Your Serger Machine

Cleaning your serger is important since it’s a cutting and trimming tool for textiles, and all materials tend to rub against one other and cause tension. Needles and threads will break if too much stress is applied, resulting in machine damage.

Use Quality Sewing Threads

It is essential to use high-quality sewing threads for a serger machine. Washing and tension may cause threads to break down. To stitch tight-fitting clothing, you may use polyester or nylon thread.

Avoid sewing on pins

Using pins to keep textiles from shifting is a common occurrence. It is, however, possible to harm the serger if you stitch over or above the pin, causing it to lose its sharpness.

Don’t Trim The Threads Near The Edges

If you use an overcast stitch sewing machine, you will be unable to backstitch if you trim the threads towards the edges. New stitches are cut when backstitch is used in a serger. Adding additional spacing from the edge while cutting threads will work if you are unable to backstitch. A method is to leave a lengthy tail of thread or chain at the end.

Avoid Hard Pushes

When sewing around curves, corners, and angles, be careful not to push too hard. If you push your foot too hard, you risk damaging or misplacing the fabric or garment you’re sewing.

Match Colors

It’s important to match the cloth and sewing needle colors while stitching. The left needle’s color should match or blend with the cloth.

Check The Machine Speed

When purchasing a serger or overlocker, check the machine’s speed to make sure it isn’t too slow. Sew at a medium pace to keep everything steady on your machine, and check the speed.

Change Threads

Use an overhand knot to swap out your sewn-in thread and cut the ends close to the spools when you’re ready to do so.

Proper Tension

After changing the threads, you can adjust the tension on an overcast stitch sewing machine.

Remove Unused Thread

Removing unwanted thread and needles and making sure they don’t fall into the serger machine are important safety precautions.
