Gutermann - 重型表面縫紉線 33碼 - #405 - 火焰紅

I used this for the decorative topstitching on a denim jacket, and the triple-ply construction made it much easier to keep the tension even. The color is a true, deep red that really stands out against the fabric.

This flame red is so vivid it makes even simple top-stitching look like a design detail. The thread glides through my machine without any fraying, and the rounded cross-section seems to give it a nice, clean finish.

The triple-ply construction makes this thread feel substantial in hand, and it handled a heavy denim seam without a single snag. That Micro Core Technology really pays off for decorative top-stitching where you want clean, uniform lines.
