Fabric Preparation

Proper fabric-strip preparation helps the binder feed smoothly and produce an even finished binding.

• Knit Fabrics: Cut binding strips across the grain where appropriate for the fabric and application.
• Woven Fabrics: Bias-cut strips are recommended when additional flexibility is required, particularly around curves.
• Cut the leading edge of the binding strip at an angle to make feeding through the binder easier.
• Keep the fabric strip flat and free from twists while feeding it through the attachment.

Recommended Machine Settings

• Sewing Speed: Moderate to slow
• Stitch Length: Approximately 3–4, depending on fabric and desired finish

How to Use the Collarette Binder

1. Turn off the machine before installing or adjusting the binder.
2. Secure the binder attachment firmly to the machine using the appropriate mounting screws.
3. Cut the leading end of the fabric strip diagonally to make insertion easier.
4. Feed the fabric strip through the binder guide according to the attachment's routing path.
5. Keep the fabric strip flat and properly aligned as it enters the folding mechanism.
6. Pull the folded binding from the outlet and position it underneath the presser foot.
7. Place the edge of your project inside the folded binding.
8. Lower the presser foot and sew slowly while gently guiding the fabric.
9. Test on a scrap piece of fabric before starting the final project.
