Quilting Threads Unraveled: Where and How They're Made

Quilting is both an art and a science, which makes choosing the right thread crucial to achieving the perfect finish. Countless quilting thread options are available, and many Canadian quilters are re-evaluating their long-standing brand loyalties in search of threads that better meet their evolving needs.

In this blog, we’ll explore the different types of quilting threads on the market, their attributes, and where they are made. We’ll also outline the uses of polyester and cotton threads, and review different weights, to help you select the right thread for your quilting needs.

Exciting news! WonderFil Specialty Threads, a Canadian-founded company, is now available at Lori’s Quilting Shop. WonderFil offers high-quality quilting, embroidery, and sewing with 36 thread lines. Whether you have go-to Glide thread colors or are looking to explore new options, I will continue to offer both brands so you can find the perfect thread for every project.

Quilting Threads Compared:  Origins, Types, etc.

Polyester vs. Cotton Threads

Polyester Threads

  • Strength and Durability: Polyester threads are stronger and more elastic than cotton, making them ideal for high-use quilts.
  • Sheen: Trilobal threads like Polyfast and Glide offer a beautiful sheen, enhancing the visual appeal of your quilt.
  • Matte/Cotton-like:  Poly wrap, cottonized, core-spun are processing techniques resulting in poly threads with a more matte  or cotton-like finish.  Examples are Ultima, Master Quilter, Omni, Premo-soft, and So Fine! in 40/50wt category.
  • Low Lint: Polyester threads produce less lint, keeping your machine cleaner.

Cotton Threads

  • Natural Look: Cotton threads, such as King Tut and Aurifil Cotton Mako, provide a traditional, matte finish.
  • Softness: Cotton threads blend seamlessly into the fabric, giving a soft and natural feel.
  • Eco-Friendly: Being a natural fiber, cotton is biodegradable and often preferred for heirloom projects.
