Product Information
Full details
The Gutermann Pure Silk Sewing Thread (688) is an essential tool for tailors, quilters, and garment makers looking for a high-end finish on delicate fabrics. Designed for fine, stylish closing and ornamental stitching, this thread offers a sophisticated gloss and professional drape. While its strength and light resistance make it highly reliable, it is specifically intended for fine detail work rather than heavy-duty upholstery, meaning it should be handled with care to maintain its soft, silk integrity.

FAQs
Can I use this thread in my serger?
Yes, it is excellent for overlock and safety seams on fine fabrics, though you should monitor tension settings.
Is this thread machine washable?
Yes, it is colour fast and resistant to light, making it suitable for washable garments when using a gentle cycle.
What needle size do you recommend?
We recommend using a size 60/8 or 70/10 Microtex or Universal needle for best results.
Is this thread suitable for heavy denim?
No, this thread is intended for fine, light-to-medium weight fabrics and will not provide the necessary strength for heavy-duty applications like denim.
Does the thread have a lot of stretch?
Silk possesses natural elasticity, but it is less stretchy than polyester threads, making it stable for structured, elegant seams.
How should I store these reels?
Store them in a cool, dry place out of direct sunlight to prevent fiber degradation and fading over time.
Troubleshooting
Thread snapping during sewing
Verify that your needle is not too thick and does not have a blunt tip; switch to a fresh, sharp size 70/10 needle.
Uneven or loopy stitches
Adjust the machine's upper tension dial to a lower setting, as silk requires less tension than synthetic threads.
Thread fraying at the eye of the needle
Ensure the needle eye is smooth and free of burrs; if the problem persists, reduce the sewing speed.

Setup, Compatibility & Care
To achieve the best results with Gutermann Pure Silk thread, ensure you are using a sharp, fine-gauge sewing needle (such as a size 60/8 or 70/10 universal or microtex) to prevent the silk from snagging. Always test your tension on a scrap piece of your specific fabric before beginning the main project. Because this is a natural fiber, avoid using aggressive laundry chemicals; wash garments created with this thread in cool water using mild detergents. Store your reels away from direct sunlight in a cool, dry place to maintain the fiber's natural luster and strength over long periods.
