SCHMETZ | 牛仔雙針 | 100/16 | 4mm

I've been sewing patches onto a heavy denim jacket and this twin needle handled the thick seams without any skipped stitches. The 4mm gap gives a neat, professional double stitch line that really holds up.

Finally got these twin needles for my jeans project and the 4mm spacing gives the perfect professional double-stitch look. The 100/16 size handles thick denim layers without bending.

Stitching denim hems went from a struggle to a breeze — the twin needles track perfectly through thick fabric without skipping a stitch. The 4mm spacing gives a clean, professional parallel line every time.
