Cutch is a wood dye from Senegalia catechu (formerly Acacia catechu), an acacia species that grows in South and Southeast Asia. The dye is both a colorant, and a traditional medicine. It is also the by-product from the manufacture of “katha”, which is a crystalline substance that is an ingredient in paan or betel nut leaf, which is an Indian mouth freshener and digestive. We’ve never tried paan, but we love cutch for its versatility and deep colors. It’s a sweet-smelling dye and the color yield ranges from … Read more

10 Tannins That Don’t Need a Mordant

There are so many mordant variations and we urge you to experiment and find the one that works best for you. If you’re not familiar with the term, mordanting is the most important process of preparing fibers to accept color.
