Getting Started with Your Baby Lock BL9
Take a look at the first critical controls: the selector and length dials. Jessica introduces the layout of the BL9 and walks through the basics of selecting the correct stitch.
The machine’s selector dial offers lettered options A through E, representing different stitches. For new users, the center-needle position (A) produces a clean straight stitch, while option B slightly shifts the needle left for advanced projects.
Understanding the Selector Dial
Turning the dial changes each stitch pattern, from straight to zigzag to stretch. You can easily see the setting by the dial pointer. The visual plate beneath helps you locate A through E patterns. The simplicity of this design makes it as intuitive as choosing a preset.
Mastering the Stitch Length Dial
The length dial adjusts between 0 and 4, with an extra gold “SS” mark for stretch stitches. Jessica notes she keeps her regular stitches between 2 and 3, adjusting higher for topstitching or basting.
For decorative functions, the SS setting unlocks additional stitch patterns ideal for knits. This stretch mode allows flexibility without breaking threads during wear or when inserting elastic.
Sewing Basic Stitches: Straight and Zigzag
Once you understand your dials, you’re ready to sew. Jessica starts with a classic straight stitch on plain woven fabric.
Executing a Perfect Straight Stitch with Backstitching
Lower the presser foot, make a few forward stitches, then press the backstitch button to secure the seam. It’s a simple habit that prevents unraveling later.
After sewing a few inches, lift the presser foot, slide out the fabric, and trim threads with enough tail for easy handling.
Now, compare that control with the zigzag stitch—perfect for finishing raw edges or creating stretch seams.
Adjusting Zigzag Stitch Width for Versatility
To switch, turn the selector dial to C. You’ll notice small hash marks between C and B; turning counterclockwise narrows the width.
Start with a wide zigzag to see how the stitch’s shape changes, then step through progressively narrower settings to understand the range.
By visually checking each sample, you’ll learn how width affects both look and flexibility. The result: a versatile seam suitable for binding edges or decorative topstitching.

Specialty Stitches for Advanced Projects
Jessica showcases other stitch letters—D and E—plus the lower-row stretch patterns. These expand your BL9’s capabilities beyond basics.
The Triple Stitch Zigzag for Stretch Fabrics
Letter D is a triple zigzag. It’s ideal for stretchy seams or when adding elastic to waistbands. The repeated stitches let the seam expand without snapping.
Invisible Hems with the Blind Hem Stitch
Letter E forms a subtle blind hem that’s nearly invisible from the fabric’s right side—perfect for pant hems or knit trims. Setting it correctly ensures professional tailoring results.
Decorative Stitching with Stretch Stitches
Moving the length dial to “SS” activates decorative stretch stitches. With knit fabric under the presser foot, these designs sew slower but flex beautifully once done.
For best results, simply guide the fabric gently. Avoid tension changes by letting the machine do the work.
If you enjoy experimenting with accessories, consider pairing your machine with specialized attachments. Enthusiasts who move into embroidery later often explore compatible tools such as baby lock magnetic hoop for easier fabric positioning when they transition into detail work.
Achieving Precision with Seam Allowance Guides
The BL9’s needle plate includes clearly etched lines for 3/8", 1/2", and 5/8" allowances—standard measurements across garment and bag construction.
Decoding the Needle Plate Markings
Each marking corresponds to common sewing standards. The 3/8" line is popular among bag makers (Jessica’s favorite), 1/2" often suits project seams, and 5/8" is the go-to for garments.
Sewing Consistent Seams Every Time
Return your dial to stitch pattern A and length 2.5, then keep the fabric’s edge aligned with your chosen guide.
When you’re done, confirm accuracy using a seam gauge—an essential verification step.
Tips for Sewing with Knit Fabrics
Knit fabrics require flexibility in stitches so that seams stretch naturally. Using the length dial’s SS setting ensures this. Remember: guide the fabric lightly instead of stretching it.
Tech enthusiasts exploring sewing upgrades might look for multi-needle options later. Some turn to accessories like babylock hoops or even magnetic embroidery hoops for brother when expanding into machine embroidery, bridging foundational sewing and advanced techniques.
Additionally, sewists frequently mention systems that simplify repositioning, such as snap hoop monster for babylock or magnetic hoops for brother embroidery machines, all of which illustrate creative expansion beyond standard sewing.
Troubleshooting Common Sewing Issues
No machine learning curve is without small hiccups. Here are a few realities every beginner faces:
- Stitches look uneven: Recheck stitch length or whether fabric feeding was consistent.
- Thread bunching beneath fabric: Re-thread the machine and confirm tension is appropriate.
- Seam width inconsistent: Verify alignment with the proper needle plate line.
If you’re gradually incorporating embroidery work, understanding compatible accessories early—such as magnetic embroidery hoops for babylock or magnetic embroidery hoops for brother—can simplify setup transitions later.

Whether you’re sewing your first seam or exploring creative stitches, the Baby Lock BL9 gives precise control and reliable results. Practice on scraps, follow Jessica’s clear method, and soon every hem, seam, and topstitch will look confidently handmade.
