TUTO UTILISER LE POINT FLAT LOCK de la surjeteuse (facile débutant & astuce technique)

Introduction

This tutorial will guide you through using the Flat Lock stitch on an overlock machine, which is especially useful for sewing undergarments like panties or shorts. The Flat Lock stitch creates a flat seam that is comfortable to wear and ideal for stretchy fabrics. This step-by-step guide is perfect for beginners looking to enhance their sewing skills.

Step 1: Adjusting the Overlock Machine

To achieve the perfect Flat Lock stitch, you need to set up your overlock machine correctly.

1. Turn the ATD knob: Set it to the letter F.
2. Choose the stitch density: Adjust it to 2.
3. Set the blade (razor) height: Position it at 6.
4. Adjust the differential feed: Set this to 1.5 to accommodate stretch fabrics.

These settings will ensure that your stitches are even and suitable for stretchy materials.

Step 2: Preparing the Fabric

Before sewing, prepare your fabric pieces properly.

1. Position the fabric: Place the fabric pieces right sides together. This is crucial for the Flat Lock stitch to work correctly.
2. Sew the Flat Lock stitch: Use your overlock machine to sew along the edge of the fabric, ensuring you maintain an even pace.
3. Trim the excess fabric: Cut approximately 2 cm from the edge of the sewn seam. This will help achieve a flat finish.

Step 3: Manipulating the Seams

After sewing, you will need to manipulate the assembled fabrics to achieve a flat seam.

1. Open the seam: Gently pull the fabric to flatten the seam.
2. Press the seam: Use an iron to press the seam flat. This step is essential to ensure the Flat Lock seam lays smoothly against the skin.

Conclusion

You have now learned how to set up your overlock machine for the Flat Lock stitch, prepare your fabric, and manipulate the seams for a comfortable finish. This technique is not only great for undergarments but can also be applied to other stretchy sewing projects. Experiment with different fabrics to master this skill, and remember to practice for the best results! Happy sewing!
