I finished this vest in just three weeks. The yarn used is Sheep Heathers in Chocolate and Cream. (Here is the link to the site http://www.shadysidefarm.com/)
The yarn is amazingly soft, almost silky, and has interesting irregularities and that special yummy smell that only a farm yarn can have. I used two skeins of each (not quite).
For the ribbing I used long a tail two-color cast-on (can be found in Nancy Bush's "Folk Knitting in Estonia"), and for the Fair Isle part - various Scandinavian patterns.
The name "Simplicity" comes from the simplicity and beauty of the yarn. I am planning to start asweater using these yarns in broader palette.
