Cotton + Steel Thread was created from a collaboration between Cotton+Steel and Sulky Thread. Since their founding in 2013, Cotton + Steel, a division of RJR Fabrics, has been dedicated to creating unique, colorful fabrics that truly bring your projects to life. This is why they chose to collaborate with such a fantastic company to create a brand new line of 50 wt. thread: Cotton + Steel Thread by Sulky. Our Egyptian Grown, Extra-Long Staple Cotton is twisted, dyed, and finished in Italy with the final winding in Germany. All 100 colors of this mighty fine, all-purpose thread were carefully chosen to include essential sewing colors plus a mix of fun, vibrant colors to perfectly match any project especially when using Cotton+Steel Fabrics. 600 yard, cleverly designed spools.
