Paper Piecing Gone Awry or Maybe I Should Keep My Suggestions To Myself

My friend L was trying a paper pieced block the other day and lamented on her blog about how it didn't turn out quite like she wanted. I've done some paper piecing so offered some, what I thought was sage, advice.
I should follow my own advice more carefully.
Behold, A9, too small and choppy on all four sides - which I can fix with sashing - but it is a rather sorry sight at the moment. I, however, am not sorry enough to throw it out and start again - not after 2 evenings of sewing and all this paper piecing!
My problem on the edges lies with my pieces being a bit too small.

However, I've stuck it to the design wall and I'm carrying on. Better finished than perfect.
