Glide 60 is a filament polyester thread that's a great choice for small letter embroidery, micro-stippling & fine-detail quilting. It makes a great bobbin thread & is produced from the same high tenacity filament polyester as our patented "Magna-Glide Classic" bobbin. It is also very fine in diameter with tremendous bendability characteristics. Glide 60 runs lint-free through your machine’s needle & tensioners. The manufacturer recommends Size 9/65 needle for its fine size & oversized eye.
