Big OOPS!!!

Is there such a thing as a band aid for a quilt????  I did a BIG BIG OOPS today.  I'm trying in my mind to figure out how to put a band aid on this one.  ;P  I was working on the quilt for daughter's graduation and I accidentally snipped the back when I was trimming a thread.  It isn't real big but there is a nice little "v" cut.  ARGH!!  Now I have to figure out how to fix it.  :-/
