Went back to the big blue shop to see what their kitchen designers could come up with for our wedge shaped kitchen.
This will be our fourth design/quote and it always goes like this.

"I'd like some ideas/quote for our new kitchen"

"Sure, have you got any sizes...........oh! it's not square, do you know what the angle is..... this might take a bit longer than normal"

So tonight he had to forget the computer and resort to paper and pencil, but came up with a reasonable design.
The ones before this have either needed a couple of days to come up with something or just given up, so some progress I suppose
