What Is the Difference Between Flatlock and Overlock Sewing Machines?

When it comes to sewing machines, there are different types and models designed for specific purposes. Two common types are the overlock and flatlock sewing machines.

The overlock sewing machine, also known as a serger, is primarily used to finish the raw edges of fabric seams. It trims the fabric edges while simultaneously stitching a seam, creating a neat and professional finish. Overlock machines typically use multiple threads, usually two, three, four, or five, depending on the desired seam type.

In contrast, the flatlock sewing machine is used to create decorative seams that lie flat against the fabric surface. It’s ideal for creating decorative edgings or decorative seams on activewear or stretchy fabrics. Flatlock machines use only one or two threads, with one thread forming the stitch on the fabrics right side and the other thread forming the stitch on the wrong side, creating a visible seam finish.

When it comes to thread choice for overlock and coverlock machines, the Madeira Aerolock Premium Serger thread is an excellent option. It’s made of 100% core-spun polyester, providing exceptional strength and durability. This thread is designed to withstand frequent washes and strain, making it perfect for use with sergers/overlock and coverlock machines.

The Madeira Aerolock Premium Serger thread is also compatible with the Janome CoverPro family of machines. These machines are known for their versatility and ability to create professional-looking hems, seams, and decorative stitches.

The overlock machine is commonly used to finish raw edges and create neat seams, while the flatlock machine is used for decorative seams that lie flat on the fabric surface.


In conclusion, the difference between a Babylock and an overlock machine lies in the brand name and specific features offered by each. Both machines serve the purpose of creating neat and professional finishes on garments, but the choice between the two ultimately depends on the individual's preferences and needs. Made of 100% core-spun polyester, this thread is designed to withstand frequent washes and strain. It’s an ideal choice for anyone looking to achieve high-quality results with their sergers, overlocks, or coverlock machines like the Janome CoverPro family.
