Gutermann - 聚酯萬用線 - 100m/110yds - #636 - 礦物藍

The color is a rich, true mineral blue that looks even nicer on fabric than in the photos. The Micro Core Technology thread glides through my machine without any breakage, making seams feel solid and secure.

I was sceptical about thread quality making a difference, but the Micro Core Technology really does keep it from snapping when I'm sewing thicker fabrics. The Mineral Blue is a rich, deep shade that matches perfectly with my denim project.

That color is exactly as pictured, a deep, saturated mineral blue that looks great on dark denim. The thread ran smoothly through my machine with no annoying tangles, and the Micro Core Technology really does seem to make it tougher than my usual spools.
