Buying Guide

Air Threading System

Threading an overlocker can be the most frustrating part of serging, especially for beginners. The Bernette Airlock series uses an automatic air threading system that pushes thread through the loopers with a simple push of a button. This feature saves time and reduces errors, making it ideal for those who want to focus on sewing, not setup.

Models like the Bernette B64 and B68 include this technology, which is a standout for anyone upgrading from a standard serger. If you’re new to serging, this can be a game-changer. For more on beginner-friendly machines, see our best starter sewing machines for beginners.

Stitch Options and Speed

Different projects require different stitches. The Bernette B64 offers 16 built-in stitches, including overlock, chainstitch, and coverstitch, while the B68 expands to 2/3/4/5 thread options for more versatility. Speed matters too: the B64 and B68 both reach 1300 stitches per minute, which is fast enough for production sewing or large quilts.

Consider what you sew most often. If you work with knits, coverstitch capability is essential. For heavy fabrics like denim, a machine with adjustable presser foot pressure ensures even feeding. If you’re exploring heavy-duty options, our heavy duty sewing machines guide has more details.

Workspace and Visibility

A well-lit workspace reduces eye strain and improves accuracy. All Bernette Airlock models feature 5 LED lights, which illuminate the sewing area without heat. The B64 offers a 130mm workspace to the right of the needle, giving you room for large projects. The free arm is handy for cuffs and sleeves, while the extension table supports bigger quilts.

For quilting enthusiasts, the B62 bundle includes a large extension table and knee lifter, making it easier to manage bulky layers. If you’re into quilting, you might also like our quilting machines guide.

Accessories and Bundles

Many Bernette Airlock models come with accessory kits that add value. The B62 bundle includes a 7-piece coverstitch foot kit, extension table, and thread bundle. The B68 bundles often include scissors, rotary cutter, and cutting mat. These extras can save you money and time, especially if you’re starting from scratch.

Think about what you’ll need for your first projects. A good foot kit lets you experiment with hems, gathers, and piping. If you’re building a sewing space, these bundles are worth considering. For more on sewing machines for garment making, check our best sewing machines for garment sewing.
