I have two alpacas, one is true black and the other is dark fawn almost brown. I don't have a rose grey - yet - but I do have some rose grey fleece - started washing it today - I just love that color! It's like a warm grey/brown.
I have plans to mix it with Dorset wool - to give it some memory. Once I card and spin it (drum carded - by hand - still looking for an electric carder) I'll be making a vest from Oat Couture - called the Oregon Vest. Since most of my shows are outside - I thought this would be a great way to showcase my fiber/yarn.
