Gütermann | 線 | 透明尼龍 | 250 m | #755 | 煙灰色

I used this for hemming a pair of dark trousers, and the smoke color really does disappear into the fabric. It's thin and strong, so my machine handled it smoothly without any snags.

The 250m spool lasts through multiple projects, and the smoke color truly disappears on dark denim hems. I used it as bobbin thread for a black dress and was relieved there was no shiny line showing.

I was surprised at how invisible this thread really is on my dark slacks—even close up, the stitch line just disappears. The 250 meter spool should last me through several projects, too.
