Use a Topstitch #90/14 needle with Variations 40 wt. thread. The Topstitch needle's large eye and deep groove protect the trilobal polyester as it passes through your machine at quilting speeds.
This needle size handles the 40 wt. weight perfectly, creating clean stitches without shredding. For longarm machines, a #14 (3.0) needle works well.
Our Titanium-coated Topstitch needles last up to 8x longer than standard needles, reducing needle changes during large quilting projects where you want consistent stitch quality throughout.
