For those new to overlocker / serging, or who have not used an overlocker / serger with a free arm, here is quick overview of what the free arm is all about and why you might want one.
Cut to the Chase
If you're looking to buy yourself a new machine, there are several models available, but our favourite Overlocker / Serger which has a free arm (and many other great features too!) is the Brother 3034DWT (click here to see a full review)
OK, now read on for Free Arm info:
What Exactly is a Free Arm
A free arm in a serger or overlocker, is, for want of a better explanation, a bit that sticks out which is a narrow, cylindrical sewing area.
Where is the Free Arm?
It is effectively created by removing a portion of the serger / overlocker’s work surface, typically the accessory storage compartment or extension table, directly below the needles. The remaining section of the serger / overlocker, which is usually narrower and has a circular shape, is known as the free arm.
The photographs, here, show examples of free arms on serger’s / overlockers.
Why do I need a Free Arm on my Overlocker / Serger?
A free arm is primarily used for sewing smaller, tubular, or cylindrical items such as selves and trouser legs, as it allows you to slide these items over the free arm, making it easier to sew in a continuous circle or loop.
It provides greater access to tight spaces, like the insides of cuffs, collars, hems, and other areas of clothing. This feature is especially useful where traditional flatbed serging / overlocking surfaces would be cumbersome.
Is it Worth Having a Free Arm?
The ability to convert between a normal flatbed serging / overlocking mode (the standard sewing surface) and a free arm mode by attaching or removing the accessory compartment or extension table adds great versatility to your serger / overlocker work.
You will be more easily able to handle a wide range of serging / overlocking tasks, making it suitable for both standard sewing projects and more specialised tasks, such as hemming and altering clothing, attaching zippers, creating decorative trims, and serging / overlocking in tight, intricate spaces.
What Types of Thing Would I Use a Free Arm for?
Some examples of things you might use the free arm on your serger / overlocker include:
Hem Circular Items: Free arm sergers are well-suited for hemming circular items like tablecloths, skirts, or dresses. The circular sewing area of the free arm allows you to maintain a consistent distance from the edge, resulting in a smooth and even hem.
Sew Piping and Trim: When adding piping or decorative trim to projects, the free arm's maneuverability makes it easier to guide the fabric and trim through the machine accurately. This is especially important for creating clean and precise finishing touches.
Sew Tight Folds and Pleats: For projects that involve creating tight folds, pleats, or ruffles in the fabric, the free arm allows you to control the fabric's movement and stitch evenly along the folds, ensuring a professional look.
Repair and Alter Clothing: Alterations and clothing repairs often require sewing in small, hard-to-reach areas such as underarms, waistbands, or necklines. A free arm serger provides the control needed for these tasks.
Sew in Zippers: While not a common function for sergers, a free arm serger can be used to attach zippers to garments or accessories. The narrow sewing area and greater access make it easier to sew zippers accurately.
Why Don’t All Overlockers / Sergers Have a Free Arm?
Good question. We don’t know! Perhaps if you have never used a machine with a free arm you find ways to work around the fiddly bits. However, once you get used to using a free arm, you would certainly miss it!
If you're about to buy an overlocker / serger then a free arm is a great feature to look out for!
Which Overlockers / Sergers have Free Arms?
If you are thinking of buying an overlocker / serger and you want a free arm we whole-heartedly recommend the Brother 3034DWT. This is a great machine if you are just starting or experienced and as well as a free arm it has an extended table facility (for very large projects) too!
