How It Works:

Unlike modern zigzag machines where the needle moves side-to-side, this attachment moves the entire fabric and feed dogs side-to-side to create the zigzag pattern. It replaces the standard presser foot and has a small lever (fork arm) at the top that engages with the needle clamp, using the up-and-down motion of the needle bar to drive the side-to-side movement.

What It's Used For:

This attachment brings essential zigzag capabilities to straight-stitch-only machines, opening up a wide range of sewing techniques that would otherwise require a different type of machine.

Primary Applications:

• Finishing fabric edges - Prevents fraying with zigzag edge finishing
• Appliqué work - Attach fabric pieces with decorative zigzag stitching
• Cording - Attach cords and decorative trims
• Decorative stitching - Create decorative zigzag patterns
• Satin stitch - Use shorter stitch length for dense satin stitch effect
• Lace attachment - Use edge guide for accurate lace positioning
• Trim joining - Precisely attach trims and ribbons

How to Use:

1. Attach: Remove the standard presser foot and attach the #121706 in its place using the thumbscrew. Ensure the fork arm at the top hooks over the needle clamp
2. Adjust width: Use the adjusting screw/lever on the attachment to set the desired zigzag width (bight)
3. Adjust length: Set the stitch length on your sewing machine to control the density of stitches (shorter length creates satin stitch)
4. Adjust tension: Slightly loosen the upper thread tension from the usual setting
5. Adjust pressure: Slightly release the presser foot pressure to allow fabric to move freely side-to-side
6. Sew: Place fabric under the foot and start sewing. Gently guide the fabric in a straight line as the attachment moves the material
