Description
- Sulky Premium Invisible thread is a very fine .004 monofilament.
- It is polyester – not nylon – and therefore, much more heat tolerant. It will not melt with normal ironing through the cotton setting.
- It does not fuzz, fray, or shrink. Use clear for lighter fabrics.
- A smaller needle such as a 10/70 is recommended.
- This product is wound on a snap spool.
