Guiding the Thread Through the Tension Disks

Once the thread has been passed through the needle, it must be guided through the tension disks to ensure proper tension. This is crucial for creating even stitches and preventing the thread from breaking or snarling. Here’s a step-by-step guide to threading the bobbin through the tension disks:

Locate the tension disks: They are two small round disks found on the top of the sewing machine, usually near the thread spool.
Identify the thread path: There will be a small notch or groove on one of the disks that indicates the correct path for the thread.
Thread the bobbin thread through the first disk: Place the bobbin thread in the notch and guide it around the disk, ensuring it goes under and then over the disk.
Thread the bobbin thread around the second disk:

Depending on the sewing machine model, the second disk may have a different design. There might be a small hole in the center of the disk or a second notch. Follow these steps based on the disk design:

Disk Design Thread Path

Small hole in the center Pass the thread through the hole

Second notch Guide the thread around the disk, ensuring it goes under and then over the disk
Adjust the tension: The tension disks can be adjusted to create different levels of thread tension. Refer to your sewing machine manual for the recommended tension setting for your project.

Disk Design	Thread Path
Small hole in the center	Pass the thread through the hole
Second notch	Guide the thread around the disk, ensuring it goes under and then over the disk

Pulling the Thread Through the Needle Hole

Threading the needle correctly is essential for successful sewing. Follow these detailed steps to ensure your thread passes through the needle smoothly:

Locate the Needle Position: Determine the position of the needle and turn the handwheel until it is in the down position.
Insert the Thread: Take the thread end and gently feed it through the eye of the needle from front to back.
Hold the Thread: As you pull the thread through, hold the end firmly to prevent it from slipping out.
Pull the Thread Through: Carefully pull the thread until it is approximately 6 inches long.

Advanced Tips for Pulling Thread Through the Needle Hole:

Adjusting the Stitch Tension for Optimal Performance

Tightening Stitch Tension

When the stitch tension is too loose, the thread will bunch up on the fabric. To tighten the tension:

Locate the stitch tension dial on the machine.
Increase the number on the dial, typically by one or two increments.
Test the tension by sewing a few stitches on a scrap of fabric.

Loosening Stitch Tension

When the stitch tension is too tight, the thread will break easily. To loosen the tension:

Decrease the number on the stitch tension dial, typically by one or two increments.
Test the tension by sewing a few stitches on a scrap of fabric.

Ideal Stitch Tension

The ideal stitch tension will depend on the fabric and thread type. However, a good rule of thumb is to have the thread just tight enough to prevent it from bunching up, but not so tight that it causes the fabric to pucker.

Positioning the Bobbin

Place the bobbin horizontally on the bobbin winder and smooth out any slack thread. Ensure it sits snugly but not tightly.

Guiding the Thread

Follow the bobbin winder’s thread guide, leading the thread through the tension disk and across the bobbin’s edge.
