The cornerstone of Double Works' products is ``Raffi,'' a yarn spun from a blend of fallen cotton. Unlike modern yarn spinning, this thread is made at a manufacturer in Osaka by craftsmen who take the time and effort to complete the entire process.

Raffi is a blend of long-fiber cotton and cotton that has been scraped off during the thread manufacturing process. In other words, it is also a sustainable thread made from recycled cotton.

Fallen cotton contains many short fibers, and when made into thread, it naturally creates an uneven feel.

When knitting fabric for sweatshirts and T-shirts using this yarn, you can create a vintage-like uneven feel and taste from an era when spinning technology was not yet developed.
