Overlock sewing thread (info and benefits)
Overlocking thread is a fine, smooth and relatively strong sewing thread designed to be used for sewing at high speeds. It can be used on the overlocker needle or looper, it’s interchangeable. All purpose overlock thread is most widely available for 250m and 1000m bobbins as well as 7500m thread cones.
Thread to use for Overlocker machines
For great results on your overlocker machine use good quality, branded, lint free thread. Overlocker thread comes on spools which are larger than traditional sewing machine spools and they are designed to stand upright on the machine. The reason you want a branded thread with the company name marked on the spool is because you’ll know the company stands behind the quality of their product.
All bobbins don’t fit all sewing machines, but most do!
Sewing machine bobbins come in different sizes, can be made of metal or plastic, and may be empty or pre-wound with thread. The vast majority of sewing machines can only use one bobbin size and, thankfully, most use the same size making them interchangeable. Consult your machine’s manual to be sure.
Best overlock thread colors to use
For ease of use try to match the tone of a fabric but not necessarily when choosing overlock thread. Example: Use a medium green thread in an overlock stich over a dark green fabric. The benefit of this approach is that the slight contrast makes it easy to see where your overlock stich threads lay.

Nylon thread is considered the strongest sewing thread due to its high strength to weight ratio. Nylon thread is a great choice for stitching upholstery, leather, and vinyl. For smooth stitches while sewing at high speed use Nylon thread treated with a friction reducer.
Strong thread is called heavy duty thread
Outside of industrial applications the strongest thread available for use in home sewing projects is called heavy duty thread. Modern heavy duty thread most often has a core made of a strong material wrapped in a more traditional thread material. Heavy duty thread is ideal for use with embroidery sewing projects.
The best all-purpose sewing thread
Before the invention of polyester thread it was common for natural sewing thread to break frequently and inconveniently. Today, most sewing machine thread has a polyester core that prevents thread breakage by making it slightly stretchy. As a result the best all purpose thread has a polyester core or is entirely made of polyester.
Cone thread use on your sewing machine
Cone thread as it’s most often referred to is just regular sewing thread on a larger spool. You can use “cone thread” on your home sewing machine though it’s likely you will first need to add an attachment to make it work properly. Cones of thread are larger than regular spools of thread and may not fit on your standard spool holder.
Regular sewing thread works in a serger (but)
You can use normal thread in a serger machine but it’s more expensive and will run out more quickly. Using overlock thread on a regular machine, however, is not recommended because it isn’t strong enough for most sewing applications.
About quilting with regular thread
You can quilt with regular thread, I often use a fine, strong two-ply 50 or 60 weight thread for piecing. I find that it allows me to sew true quarter inch seams. 50 weight thread works but you can sometimes see your stitches so use the 60 weight, or even bigger 80 or 100 weight thread, when possible.
