Jeans Stitch #015 - Soft Green Spool

Jeans Stitch is our 12 wt. heavy-duty thread designed for sewing on denim, canvas, upholstery, and other heavyweight fabrics. Made from spun polyester, it is a strong, bold thread. If you've ever had a thread snap while hemming jeans or making bags, you'll love how Jeans Stitch powers through multiple layers without giving up. It creates bold, visible stitches that look professional and hold up to heavy use and repeated washing.

While designed for heavyweight fabrics like denim, canvas, and upholstery, you can use Jeans Stitch on regular fabrics for bold, decorative topstitching. Think about adding contrast topstitching to a jacket, creating visible seams on bags, or adding decorative details to home décor projects. The key is using the right needle (Topstitch #100/16) and adjusting your stitch length slightly longer (3.0-3.5mm). Just keep in mind that Jeans Stitch creates visible, chunky stitches, so it's not the best choice if you want a subtle stitch. Use it when you want your stitching to make a statement.

Jeans Stitch is a heavy 12 wt. thread designed for couching and serger loopers rather than as a needle thread. For couching, lay the Jeans Stitch on top of your fabric and tack it down with a finer thread like Precision 60 wt. or invisible thread using a zigzag stitch. This creates bold, dimensional lines without the stress of pulling heavy thread through your machine's tension system. In serger loopers, Jeans Stitch creates dramatic, visible edges on denim projects, bags, and home decor. The heavy weight stands out beautifully on fabric edges where you want a decorative finish.

When couching Jeans Stitch, use Precision 60 wt. or invisible thread in your needle to tack down the heavy 12 wt. thread. The fine couching thread disappears into the Jeans Stitch while your bold decorative thread takes center stage on top. Use a [Topstitch #70/10 needle](https://ylithreads.com/collections/needles/products/70-10-titanium-coated-topstitch-needles) for the couching thread. Set your machine to a medium zigzag stitch that catches both edges of the Jeans Stitch as it lays on your fabric. This technique gives you the look of heavy topstitching without the tension challenges of running 12 wt. thread through your needle.
