How can I break up a 'woody' room?

[CakeInMyFace]

I have lots of wooden furniture in my dining room, wood floor, wooden bookcase, wooden cabinet & hutch. Yesterday when I got home I realised it really needed something to break this up a bit. I was thinking a splash of colour with a nice tablecloth (preferably cotton rather than pvc one). My walls are a creamy white / yellow, and the dining room opens up through an archway to my sitting room where the walls are a terracotta colour.

I was thinking of this green gingham one, but really not sure about it. Any suggestions on where I can find something and what sort of pattern / colour to go with? Home decorating is definitely something I struggle with!
