Choosing the Right Serger Thread

Choosing the right serger thread for a project is as important as choosing the right serger for yourself. It’s essential to buy the best quality thread you can afford. The low tensile strength of cheaper threads allows lint and fuzz to build up faster. Serger thread is sold on large spools holding between 2,000 to 3,000 yards of thread because so much is used during the serging process.

These threads are designed to be used in multiples of two or more spools because they have dual duties: to construct a seam while finishing the raw edge of the fabric. Serger thread is finer than standard sewing machine thread to avoid the bunching and pulling that cause bulky seams. Using multiple spools of thread ensures the end seam, hem or finish will be flexible, durable and strong.

 

Polyester is the most widely used type of thread for serger machines due to its strength, durability and flexibility. However, some projects might call for a different type of thread, such as nylon, cotton, wooly nylon or other thread types. It’s easy to become intimidated by the amounts of thread used in serging, but the end results are more than worth the effort and cost. Here is a look at several popular polyester brands of serger threads that vary in quality and price.

How to Choose Serger Thread

Material

• Polyester (most popular)
• Nylon (great for elastic fabric e.g. swimwear)
• Cotton (not as strong as polyester)
• Wooly Nylon (great for elastic fabric e.g. swimwear)
• Poly-wrapped Poly Core

Color

Serger thread is available in basic colors and different shades and blends.

Smoothness

Serger thread should be smooth so it navigates through the serger easily. Polyester is popular for this feature while cotton is not due to the short fibers which can be messy.

Price

As with anything you get what you pay for and the cheaper serger thread can do as little as create a messy situation to damaging a serger. If within your budget go for the higher quality serger thread.

About Amanda S.: Growing up, I was fascinated by watching my mom and grandma turn fabric into beautiful handcrafted items. In my early 20’s, I finally got brave, buying a sewing machine and teaching myself to sew. As I fell in love with sewing, my machine collection expanded, and I ran an Etsy shop sewing children’s clothing for a few years. As a single mom of 3 great kids, my sewing time has lessened, but I still try to find time to work on quilts, bags, and projects with my kids, teaching them what I love.
