Why? Why?!

I am two rows away from finishing my Flower Basket Shawl and I ran out of yarn!!! I can rip out the edging and the last repeat and reknit the edging or I can find another yarn to finish the shawl with. I'm going to look around at work tomorrow and see if I can find something I can live with. The ripping just sounds too painful right now. I'm also worried that my shawl is a wee bit small so I don't want to make it even smaller. Sigh...
