What a Serger Actually Does

Do you really need a serger? Let’s talk.

Here’s what a serger does (and why it’s not a must-have right away).

If you’ve been sewing for a bit, you’ve probably heard people rave about sergers.
But what do they actually do?

A serger (or overlock machine) trims, sews, and finishes fabric edges all in one pass.
It uses multiple threads — usually three or four — to wrap the edge of the fabric, locking the seam and preventing fraying.

That’s why your store-bought clothes have such clean, stretchy seam finishes.

A serger is incredible for knit fabrics, like t-shirts or leggings, because it can stretch with the fabric without snapping.

It’s also much faster than a regular sewing machine.

But here’s the truth: you don’t need one to start sewing.
Your regular machine can handle most projects beautifully.

You can finish raw edges with a zigzag stitch, pinking shears, or even French seams.

Think of a serger as a bonus — not a requirement.

Once you start sewing garments regularly, you’ll love having one.
But until then, master your main machine first.

Because the best tool isn’t the fanciest one — it’s the one you know how to use well.
