Can I use a 12wt rayon thread in my sewing machine?

Yes, 12wt is the heaviest weight of thread that fits through the eye of your sewing machine needle. Using a 12wt for your project gives more richness and dimension. For best results, use a larger needle—we recommend a 90/14 top stitch.

What types of projects is a 12wt rayon thread best for?

A 12wt rayon thread is perfect for embroidery, topstitching, quilting accents, decorative stitching, decorative seams, or any project where you want more visible stitching.

What is the difference between using 12wt vs 40wt in your project?

A 12wt thread is thicker and more visible, making it ideal for decorative work and giving your project more of a pop.

Is rayon thread strong enough for heavy fabrics?

While WonderFil rayon is durable, it’s best for decorative rather than structural purposes. For heavy-duty stitching like Home-Dec, we recommend a stronger thread.
