This is not a pattern so much as a kind of general direction for how I adapted Elizabeth's Moccasin Sock for my own purposes.  I used 4 oz of superwash merino roving that I got from Portland Fiber Gallery www.portlandfibergallery.com or portfiber@etsy.  You can use sock  yarn or spin your own if you like.  This merino superwash spun up beautifully and washes and wears well.
