For starters the pattern has a left and right side chart. You don't need both these charts as the shawl is symmetrical and one chart works for both sides. And as for the double YO's at the peak, I purled into them so as to twist each stitch. this worked much better than knitting and purling, makes a cleaner, more consistent stitch.
Then the pattern says to repeat it 7 times. I had one skein of yarn so did 6 repeats as one is not quite enough to get 7.
It says to repeat the chart. But you will make the full chart on the 1st repeat and then after that you will only need to repeat rows 23-37. I made a line to mark this on my chart. This is a small clip of how I drew my lines for the repeats. I repeat the center part as many times as needed and when headed twards the peak or end I then followed the chart to the edge (ignoring the stitches in the yellow poriton). This is my marked on chart but you can transpose the lines to your chart.

The pattern says to repeat and end on row 33. I ended on row 35. On the last 2 pattern rows you need to do the peak slightly different. On row 33 make 1 YO instead of 2. and at the peak on row 35 I did yo, k1, yo. this will set you up to easily make the border.
Because by knitting up to row 35 you will need to start the border chart on row 5.
Here is a photo before blocking. You can click on them for super sized images.
And after blocking. I, again, used my steamer and blocking this way was really fast, I was able to unpin it as soon as I was done steaming it.
