The yarn I used was "Bernat's Soft Boucle", but you could use and yarn that looks like a ferret's fur. For the body,(the scarf part)I cast on 15 stitches and continued a k1,p1 pattern thoughout every row untill I got my desited length.
The legs I made seperatly with 4 or 5 cast on and contuned the rectangle for about two inches(changing yarn color for the fur patterns of course) and used the yarn ends to "sew each to the body. (2 on each end).

The tail I braided
