Edging for my KISS PI Shawl

I finally settled on an edging for my KISS PI shawl. I think this picture shows the subtle variegation in this yarn. This is not the simplest edging I could find, but it is the one I liked. As you can see, I have finished 2 repeats. I check my chart and make a tally mark for each row so I know where I am. Perhaps after another 15 or 20 repeats I'll be able to leave the chart behind. With our new puppy in the house, I can only knit a few rows at a time, so it may be quite awhile before I get into the rhythmn of this edging. I really wanted to have it done by now, but I just can't set aside the same amount of knitting time as I used to.
