But the Bernette B68 Maker Airlock changes that.
We'll walk you through what makes this machine so approachable and why it’s such a perfect addition to your sewing studio.
The B68 Airlock is a combo machine, meaning it functions as both an overlocker (serger) for finishing seams and a coverstitch machine for professional hems and topstitching. Instead of needing two separate machines, you get both capabilities in one streamlined setup.
Designed with the sewer in mind, the tools like tweezers, needle threader, and needle storage are built right in, making finding your tools and setting up the machine even easier.
One of the standout features of the B68 is how easily it converts from overlock to coverstitch. Instead of a complicated overhaul, the process is straightforward:
Coverstitch is what gives you that ready-to-wear look on hems, cuffs, and seams, like the stitching you see on t-shirts and athletic wear. It creates clean, parallel stitching on the front and a stretchy, secure finish on the back that is perfect for hemming knit garments, finishing sleeves and waistbands, and adding decorative topstitching.

Why We Love This Machine
Let’s be honest, the hardest part of using a serger is usually threading it. That’s where the air threading system comes in. With the push of a button, the machine literally blows the thread through the looper system. No digging around, no frustration, no guesswork. Even better, the threading paths are color-coded and the tension settings are clearly marked!Designed with the sewer in mind, the tools like tweezers, needle threader, and needle storage are built right in, making finding your tools and setting up the machine even easier.
In overlock (serger) mode, the B68 trims the fabric edge while stitching, creating that classic finished seam you see inside ready-to-wear garments. It’s ideal for:
- Garment construction
- Seam finishing
- Stabilizing edges before quilting
Overlocking the edge creates strong, flexible seams, perfect for knits. Since it cuts as it sews, it creates beautifully clean, professional looking edges. This machine can also handle a wide range of materials, from lightweight cottons to denim and fleece, making it a versatile workhorse.
One of the standout features of the B68 is how easily it converts from overlock to coverstitch. Instead of a complicated overhaul, the process is straightforward:
- Swap out the stitch plate/cover
- Adjust a few tension settings
- Reposition needles
- Disable the upper looper
Coverstitch is what gives you that ready-to-wear look on hems, cuffs, and seams, like the stitching you see on t-shirts and athletic wear.

Is the B68 Airlock the right machine for you?
It well might be if you sew garments regularly, want more professional finishes, feel intimidated by traditional sergers, or simply want a machine that can do more in less space. And if you needed a little more persuading, consider that the Maker edition comes with lot of extra perks, including an exclusive accessory set, an extension table, and even a mini-vacuum cleaner to help keep your machine free from lint!
