Pics to follow when I have added the fringe.
I knitted up the extra 54 rows in the 3rd repeat and measured. It was 150 cms or so and when I tried it on, it was the perfect size for wrapping around my neck a couple of ways. I don't want this to be a shawl, but a long scarf that I can wear as a stole indoors or wrap around my head and neck when it is too cold outside. It works as all three at this size. So I bound it off.
Next step is to do a couple of rows of crochet on the short edges to provide a place to anchor the fringe and then add the fringe. The pattern calls for crochet all the way around but I like the rolling at the long edges. It is wide enough that the rolling doesn't make it too narrow. So, like some of my friends who have made this, I am going to only crochet along the short edges.
