Blues - to be written in installments

So, here we have a very unpromising looking sac of yarn - it's an old pillowcase:









And here's what lives in it.
The whole mess of yarns started off with a huge skein of Ellen Minard's spaced-dyed mohair, which comes in a 1 lb. skein. I don't know what the color way was called at the time, something blue, purple and black.
Over time I assembled a bunch of Green Mountain Spinnery Mountain Mohair, Brown Sheep Lamb's Pride, cotton chenille which I have long since lost the labels to, and other odds and ends of wool, mohair, cotton and blends.
