Running out of yarn

So I have 24 rows left to go on my scarf to have the stripped pattern match and be symmetrical. I need abut 10 feet of purple yarn to create 8 rows of that 24. I have only 4 feet left. And at 13 dollars for a hank, plus a trip to SoHo to see if they even have the color left in stock... I'm just not about to spend the money or the time on it. I hate that I came up that short though. Just a slight frustration on this night that I need to be calm and centered.
