OK - well good news and bad news ('sh) on the material front.
- the good news is that I just about have enough of the main (Brick coloured) fabric - phew!
- the not so good news is that I dont have enough Burgundy Leatherette for the front lower edge. However....

I think that I will get away with that and it saves all the hassle/worry of colour matching, waiting for delivery etc etc
This is what I am planning - you can see the proposed stitch lines in Black marker on the original item:
