Trees are growing on paradise island!

Here's the last photo I posted of my Paradise Island cross stitch pic.  As you can see here, I'd finished as much of the water as I'd planned to do at this point and moved on to putting in some of the tree section on the distant shore.

Not surprisingly, after that came some more trees:

And then some more:

I've managed to straighten up the warped bottom section a little, but I realise I'm probably going to face the same problem at the top and, as this will probably be a cushion cover to brighten up a new sofa in our new home (ONE day!  I wish I knew when we were moving and we could just get on with it!), it's all going to need to be wet stretched for a while on completion.  Given that not all of the squares will be 'filled in', I'm wondering how, or indeed if, that will work out.  Anyone got any tips or experience they can share?
