Almost finished

Well, I got the body of the shawl done and went to do the border and realized I won't have enough yarn to do it. :( So, I'm trying to decide what to do, since I can't get anymore of the colorway, that I'm using. I figure I can get about 3 more rows across, maybe 4...I would like to at least have a lace border on it, since that is what the pattern calls for, but don't know of any 15 stitch 3 row lace patterns. If anyone does, could you let me know?
