Gutermann 聚酯纖維萬用線 500m/547yd #115 鐵灰

I'd been having trouble with cheap thread snapping mid-stitch, but this 500-meter spool is so strong I've sewn through denim without a single break. The grey is a perfect neutral for most of my projects.

The Micro Core Technology made this thread glide through my machine without any tangling or breaking, even on thicker denim seams. The 500-meter spool is great value for the price, and the grey shade blends perfectly with my project. The smooth finish really makes a difference in stitch quality.

I was skeptical about spending a little more on thread, but this polyester spool is incredibly strong and the 500 meters will last through many projects. The Micro Core Technology really does make a difference in preventing breakage.
