Gutermann - 聚酯纖維萬用線 - 100m/110yds - #637 - 北極之夜

This Arctic Night shade is a proper midnight blue, not a wishy-washy navy, and the thread feeds through my machine without a single snag. The polyester has just enough give that my seams don't pucker on stretchy knits. It's become my go-to for all the dark-toned mending in the house.

That Micro Core Technology really delivers — I was sewing a tricky denim seam and the thread didn't fray or snap once. The color is exactly the deep blue-black I needed for a winter coat lining.

This spool of Arctic Night glides through my machine without any of the skipped stitches I used to get. The Micro Core Technology really makes the thread feel stronger and less likely to snap when I'm sewing thicker layers.
