These can be for the shawl, the shawl OR Natalie's wild version of by Petite Knits. 

The patterns are not included with the yarn bundles.

If you chose a "like so-and-so" it will have the same overall appearance.  The exact skeins can vary drastically... and some colors are very similar to one another.  

If you plan to do the top, it is enough yardage for the XL if you are on gauge and you will need to modify your stripe sequence.  Some people are adding another skein in a different color, whereas others are adding another skein of one of the colors that is used when you are dividing the armholes.  See my ravely page above for my notes on how I did it.  I debated doing the bold stripes and thought a fade from one color to the next would look really nice too...
