3. Setup and Usage

To achieve optimal results with Coats Eloflex Stretch Thread, follow these guidelines for setting up your sewing machine:

3.1 Threading Your Machine

Use Coats Eloflex Stretch Thread for both the top thread and in the bobbin. Ensure your machine is threaded correctly according to its manufacturer's instructions. The unique elasticity of Eloflex allows it to stretch with the fabric, creating a flexible seam.

3.2 Needle Selection

Proper needle selection is crucial for sewing with stretch thread. For most applications, a universal or ballpoint needle is recommended to prevent damage to knit fabrics. Refer to the product packaging for specific needle size recommendations:

• Machine Needle: 11/14
• Hand Sewing Needle: 7/8

3.3 Tension Adjustment

Start with your sewing machine's standard tension settings. If you experience skipped stitches or uneven tension, make small adjustments to the upper tension dial. Test on a scrap piece of your fabric before sewing your final project.

4. Operating Guidelines

Coats Eloflex Stretch Thread is designed for use with a normal lock stitch. No special stitch settings are typically required, as the thread itself provides the stretch. For best results:

• Fabric Compatibility: This thread excels with stretchable fabrics. Ensure your fabric has sufficient stretch for the desired outcome.
• Seam Strength: The thread creates secure and robust seams that can withstand stretching without breaking.
• Testing: Always perform a test stitch on a scrap piece of the actual fabric you will be using to verify tension and stitch quality.

5. Maintenance and Care

Coats Eloflex Stretch Thread is designed for durability and ease of care. Garments sewn with this thread can be machine washed without compromising seam integrity or color.

• Washing: Machine wash garments as per fabric care instructions.
• Bleaching: The thread is colorfast and resistant to chlorine bleach.

6. Troubleshooting

If you encounter issues while sewing with Coats Eloflex Stretch Thread, consider the following common solutions:

• Thread Breaking:
  • Ensure your machine's tension is correctly set. Too high tension can cause thread breakage.
  • Verify that you are using the recommended needle size (11/14 for machine, 7/8 for hand sewing) and that the needle is not bent or dull.
  • Check for any burrs or rough spots on your machine's thread path that might be snagging the thread.
• Skipped Stitches:
  • Re-thread your machine completely, ensuring the thread is seated properly in all guides and tension discs.
  • Change to a new, sharp needle of the correct type and size for your fabric.
  • Adjust the presser foot pressure if your machine allows it, especially for very stretchy or slippery fabrics.
• Seam Not Stretching:
  • Confirm that Eloflex thread is used for both the top and bobbin.
  • Ensure you are using a normal lock stitch. Some decorative stitches may not allow for full stretch.
