As the hanks of recycled silk yarn are made individually, each one is unique. There's no dye lot on recycled silk yarn, and even if you buy two hanks at the same time there's no guarantee that the colors are going to be the same.
But really that is the beauty of using recycled silk. Each piece has its own individuality and everything you make from the yarn is its own work of art, completely unique.
