American made yarn from Colorado grown Suri alpaca fiber mixed with 20% Tussah silk. The Tussah silk has it's own golden shean which makes the difference in these two yarns a little tough to see. In the photo, the Brown is the yarn to the left (labeled Brown+White). Copper is the yarn to the right (labeled Dark Fawn). Brown is just a little darker, with a touch of grey. The Copper is lighter.
