Notice the bit laying on the floor. I measured the cowl when I was laying it on the bed to match the ends without any twists. It was just a rough measurement when I had matched the ends and then folded it again.
It was approximately 31 inches.
And since it was folded over in fourths, that would make....gulp....120 inches.
I went ahead with the three needle bind off.
I do like the ridge it makes in the separation between the beginning and ending of the season.
