SO. Close.

Look at that second sleeve.  Lovely isn't it. 

Now look at that bit of yarn up there.  That is the end of the last ball of black yarn. 
Now look at the few inches left of knitting. 
Now imagine how I feel. 
Argh!  The yarn is on back order.  Of course.  There is one person on Ravelry who has half a ball in her Trade/Sell stash.  I've messaged her.  I'm not holding my breath it's been in her stash for two years and could be gone by now. 
Will this sweater ever be finished?!
