Edging for FF&L

I am now working on the edging for the Frost Flowers & Leaves shawl. If I calculated correctly, the edging will take about 21,600 stitches. For the rows where you are suppoed to PU a stitch for the wrap, I am doing a cable instead. I did the wrap stitch, but this did not look as clean as I wanted it to so I switched to a cable. This does not look that great either, but hopefully when the shawl is blocked, it will look close enough to the picture in the book.
