FAQs
What is Bulky Lock 80 thread best used for?
It is best used for creating soft, elastic seams on overlock and coverlock machines, and for covering cut edges on various fabrics, especially knits and stretch materials.
Can I use this thread on a standard sewing machine?
No, this thread is specifically designed for overlock and coverlock machines. Its bulk and elasticity are optimized for these types of machines and stitches.
How do I adjust my machine for this thread?
You may need to adjust the tension settings on your overlock or coverlock machine. It is often recommended to slightly decrease tension on the looper threads. Always test on a scrap piece of fabric first.
Is this thread suitable for very fine fabrics?
Due to its bulky nature, it is generally not recommended for very fine or delicate fabrics where a fine seam is required. It performs best on medium to heavier weight materials.
What does '80' refer to in Bulky Lock 80?
The '80' typically refers to the thread's thickness or construction, indicating it is a substantial, bulky thread designed for specific sewing applications.
How long is the thread on one spool?
Each spool contains 1,000 meters of thread.
Can I use this thread for topstitching?
While it can be used for decorative topstitching on an overlocker or coverstitch machine, its primary function is for seam construction and edge finishing where softness and coverage are key.
Troubleshooting
Thread breakage during sewing
Check machine tension settings and reduce tension slightly if too high. Ensure the needle is sharp and correctly inserted. Verify that the thread is feeding smoothly from the spool and is not snagged.
Uneven or loose stitches
Adjust looper tensions, typically lowering them slightly for bulky threads. Ensure the thread path is clear and that the presser foot is applying appropriate pressure.
Skipped stitches
Ensure you are using the correct needle type and size for your fabric and thread. Check that the needle is not bent or dull. Verify that the machine is correctly threaded.
Poor coverage on cut edges
Increase the differential feed slightly to help spread the fabric. Adjust the cutting width and ensure the looper threads are set correctly to enclose the edge fully.

It is recommended to perform a test sample on scrap fabric before starting your project. Generally, slightly lower tensions might be required on the looper threads for optimal coverage and softness.

Compatibility:
- Fabrics: Ideal for medium to heavier weight fabrics, knits, stretch fabrics, fleece, and performance wear.
- Projects: Best suited for seams, hemming, edge finishing, and decorative effects on garments, sportswear, swimwear, and home textiles.
