The Baby Lock Plain Hemmer 1/4" (Part Number: B0421S07A) is a time-saving metal attachment designed to automate fabric folding. It automatically guides and folds a straight edge into a precise 6mm (1/4") double-turn hem, eliminating the need for tedious manual pinning or pre-ironing.
3 Sewing Applications
-
Garment Hemming: Creating neat, uniform bottom hems on lightweight shirts, casual blouses, and skirts.
-
Home Textiles: Constructing clean, crisp borders on home décor items like table runners, fabric napkins, and lightweight curtains.
-
Long Panel Edging: Speeding up production on long, straight fabric edges like apron ties, ruffles, and tiered dress panels.
Recommended Application Methods
-
Mounting: Screw the plain hemmer securely onto your machine's base plate using the two white thumb screws provided with your machine.
-
Fabric Prep: Cut the starting corner of your fabric at a slight angle. Manually fold it twice to a 1/2" width to form a starter tail.
-
Feeding: Slide this folded tail into the spiral funnel scroll of the hemmer, pulling it completely under the presser foot.
-
Stitch Selection: Set your machine to a Wide Cover Stitch (C1-C3 combination) or a Left Chain Stitch.
-
Operation: Keep your hands relaxed, lightly guiding the raw edge into the right side of the scroll while sewing at a moderate pace.

User Q&A Scenarios
Q1: The fabric edge is slipping out of the scroll and leaving raw edges un-hemmed. How do I fix this?
Solution: This happens if the fabric is not fed deeply enough into the attachment. Gently guide the raw edge slightly to the right as it enters the spiral funnel, ensuring the scroll remains completely filled with fabric.
Q2: Can I use this hemmer to finish heavy wool jackets or thick denim jeans?
Solution: No. This accessory is strictly engineered for light to medium-weight woven fabrics like cotton, linen, and lightweight chambray. Heavyweight fabrics will jam and choke the narrow spiral opening.
Q3: Where can I get this genuine Baby Lock accessory?
Solution: You can buy this authentic attachment online or physically in Singapore from authorized retailers such as Sewing.sg (operated by Ban Soon Sewing Machine Pte Ltd) located at 431 Clementi Avenue 3, #01-328.
Q4: What is the price of this specific B0421S06A attachment in Singapore?

3 Safety Precautions
-
Cut the Power: Always turn off the machine’s main power switch before installing or adjusting the hemmer to avoid accidental needle punctures.
-
Clear the Needle Space: Keep your hands, pins, and metal tweezers away from the moving needle bar while pressing the foot pedal.
-
Disengage the Blade: Ensure the upper overlock cutting knife is locked down or disengaged so you do not accidentally slice your fabric.
