An overlocker, also known as a serger, is a great way to give your sewing projects a professional level finish. Overlock Threads are brilliant at strengthening seams on knit fabrics or for hemming, it will work just as well on wovens. You can use it for a clean finish to your seams, and also for neat hems.

Overlocking thread is different from regular sewing machine thread. In fact, it’s the thread that often makes people feel intimidated by these machines! Unlike a normal machine, an overlocker uses large cones of thread – usually three or four known as Overlocking Cones.  You will not be able to use a regular bobbin of thread on this machine. This works both ways: if you’re trying to thread your sewing machine with overlocker thread, you can damage it and cause major problems to your project. Be sure to always use the correct sewing cotton for the task at hand! Overlock machine thread is a bit thicker than all-purpose thread used to create a Lockstitch and often used in Bridal Wear in the UK.

If you’re looking to buy overlocker thread, first check how many cones you’ll need for your particular machine. Many users of overlocking cotton prefer to buy their cones in a few standard, useful colours such as black, white and grey, rather than carefully matching the shade of the fabric like you would with the thread for a sewing machine. This is because the overlocked stitches will be on the inside of your garment, invisible from the outside.

Machine Thread & Sewing Thread

Thread for your overlocking machine is sold in large cones, so you won’t need to stock up so often. To take the intimidation out of using your overlocker, you might want to work on several projects with a similar colourway, so you don’t have to change the thread too much. However, experienced serger users offer some advice to make your life easier when you’re threading the machine:

Check your overlocker manual for guidance about how to thread your machine. This can be a difficult process if you haven’t used serger thread before, as there are many more steps than with a sewing machine! However, once your overlocker is up and running, there are a lot of helpful ways to keep your sewing thread in place. The eyes of the overlocker needles are much larger than on a sewing machine, so when you want to change thread, many users recommend tying thread ends together and passing the knot through the needle, rather than going to the trouble of threading the machine again.

Many users stick with polyester overlocking thread, just like they do with a sewing machine. However, depending on the nature of your project, you might find that it’s better to try nylon overlocking thread. As always, look for a lint-free thread to avoid causing internal problems for your machine. Just like a sewing machine, an overlocker can suffer from a build-up of dust and lint, and this can lead to skipped stitches, bird’s nesting thread, and other problems.

If you’ve never used an overlocker before, it’s definitely worth giving it a go! Once you get used to using these machines, they can really improve the appearance of your projects, giving you amazing, professional-quality finishes. An overlocker is also essential if you’re using 4-way stretch fabric. You might have no problems constructing a jersey dress or T-shirt on your sewing machine, but if you’d like to make a swimsuit, leotard or sportswear, then it’s essential that the seams don’t pop under strain. An overlocker brings major peace of mind to your projects. If you’re really scared about figuring out how serger thread goes into the machine, remember that there are dozens of Youtube tutorials available nowadays showing you just how to do it.
