I was very lucky that the yarn I used striped the Shawl perfectly. Here is the label from the yarn I bought at Joann's:

It it a Boucle yarn and I used a J hook.
Here are two views of my finished Shawl:


If you are a beginner, I would not recommend using a Boucle for this project, as you might be able to see your stitches better with a smoother yarn. If you do use this yarn and you plan on crocheting in public as I did, I would recommend that you roll this yarn into a ball before you leave, as it had a tendency to tangle, in the close confines of an airplane, since it was such a large ball of yarn!! (11 ounces).
I can't wait to try this Shawl in another yarn that is not a Boucle, so I can really see the stitch definition in it. I also think that because I know the pattern stitch so well now, it will go even faster!
