The yarn for this design is Ancient Arts Fibre Crafts Merino/Cashmere/Nylon fingering weight. Let me tell you, this yarn is so nice to work with and wear! The colors are Lapis Lazuli (the blue) and Vancouver (the variegate).
This pattern is easy, but uses an interesting stitch, which you can see fairly well in the close-up below. These are shell stitches that sit on top of each other, instead of sitting down in the "valleys" of the row below.
This long and wide scarf doubles as a wrap, so you can style it either way and it looks really great!
You can purchase this pattern through Ravelry, or on Ancient Arts' website.
