Mettler 絲光棉線 50支 164碼 潛水藍

I’ve been using this 50 wt thread for piecing a quilt and it glides through my machine without any fraying or breakage. The Snorkel Blue shade is vibrant and the mercerized cotton feels strong even under tension.

This thread glides through my machine like butter, and the 50 wt weight is perfect for piecing without any fraying. I've washed a test quilt twice and the Snorkel Blue hasn't faded a bit.

The color is exactly that watery blue I wanted, and the mercerized finish glides through my machine without a single snap. It’s held up beautifully through two washes on a quilt, so the colorfast claim seems legit.
