Well, I did the numbers for the clapotis and realized that I was right to worry. Not enough yarn to continue. So, last night, while watching the Red Sox dominate in game 6, I ripped it all out and started it all over making it less wide. It is now normal scarf size rather than being too wide. Now I can make it nice and long like I like without running out of yarn. I am already at the length I was on the wider version and have only started on my second ball of yarn. I am feeling much better about this thing now.
I think I will work on it some more tonight during Game 7.
