Aurifil Endangered Species Color Builders Thread Club 40 WT
The Aurifil Endangered Species Color Builders Thread Club 40 WT were created in part to herald and highlight the very first thread weight produced by Aurifil: 40wt.
They are a capsule of 12 mini-collections dedicated to an incredibly worthy cause that falls in line with our goal to increase Aurifil’s sustainability and positive environmental impact — Endangered Species.
Each collection contains three large spools of our supple and strong 40wt thread — a warm, a medium, and a dark.
