This guide is for sewists using overlock or coverlock machines who need a high-quality, elastic thread for soft and professional-looking seams. The Gutermann Bulky Lock 80 offers excellent coverage for cut selvedges, ensuring a clean finish. A key benefit is its elasticity, which allows seams to stretch with the fabric. However, users should note that its bulkiness may require adjustments to machine settings.

This thread is specifically designed for use with overlock (serger) and coverlock (coverstitch) machines. Its properties are optimized for these types of machines.
While technically possible, it is not recommended. Bulky Lock 80 is a thick, textured thread designed for the specific stitch types and tension requirements of overlock and coverlock machines. It may cause issues or not perform well in a standard sewing machine.
It is ideal for knit fabrics, stretch materials, activewear, and garments where soft, elastic seams are desired. It also works well for finishing the edges of medium-weight woven fabrics.
The elasticity allows the seams to stretch along with the fabric. This prevents stitches from breaking or pulling when the garment is worn or stretched, making it perfect for activewear and knits.
Generally, standard overlock or coverstitch needles are sufficient. However, due to the thread's bulk, you might achieve better results with a slightly larger needle size or a needle specifically designed for thicker threads. Always refer to your machine's manual.
'Bulky' refers to the thread's thickness and texture, designed to provide fullness and softness. 'Lock 80' indicates its construction and suitability for overlocking (60 or 80 usually indicates thread count/thickness for serger threads, with higher numbers generally being finer but this is a bulky type).
Ensure your machine's tension is correctly set – often slightly lower for bulky threads. Using differential feed can also help manage fabric feed and contribute to softer, less puckered seams.
Check for burrs on the machine's feed dogs or needle plate. Ensure the correct needle size is used and not damaged. Verify thread path is clear and tension is not too tight.
Ensure the correct needle type and size are installed. Check that the machine is threaded correctly. Clean the machine's loopers and ensure they are properly aligned.
Reduce the tension on the relevant loopers. Ensure you are using the correct settings for a bulky thread. Consider using a finer thread for differential feed if puckering is an issue.
Ensure the thread is feeding smoothly from the spool. Check for any snags or knots in the thread path. Adjust thread tension if necessary.
