The areas on a full hide do vary and yes the outer parts and under belly area are usually softer but this is useful when re-uphostering as these parts of the hide can be selected for specific areas say an armrest where the leather needs to be stretched, contoured and formed more into shape. Again though modern leather production processes split the hides into controlled thicknesses and can roller them to maintain an even thickness.
One of our departments jobs (essential too for piece price costing) was to maximise the parts that could be used on a car from the hide. Selecting the right part for the hide area was also key. The planned cut pattern which looked more like a jigsaw would then be tooled or programmed into a CNC robot cutting machine.
Hides can be dyed in colour or surface coated on top of if I recall what they termed blue hide or white hide which is what they all turn out like after the tanning processes depending what modern chemical process used nowadays.
The dyes penetrate all the way through as the hides are just soaked in big vats. The top surface coated coloured hides will generally show a difference of colour on the reverse sueded side. A lot of technology has gone into modern leather surface coating..... http://www.bader-leather.de/cms/index.p ... 61&clang=1
Both are used in the auto industry and my Rolls Royce leather is actually just a tan colour under the Catkin green top surface finish. After 40 years the drivers seat showed some wear through and I just reconnolised the surface. At the time Connolly were still in business and provided me a kit. Now there are companies like Gliptone providing the same surface refinishers and I do believe some ex Connolly workers continued the right to produce and market Connolly restoration products.
I would think if yours are Moroccan hides they will be from the traditional old tanning processes which included soaking the hides in pigeon droppings and urine
Any leather re upholsterer will know the best areas of the hide to select for certain parts of the seating but I would not be too concerned about surface finish resistance to scratching.
As I mentioned before though, don't assume you can just do this on any sewing machine, especially if you have got full hides as even if lambs skins they can still be quite thick in places.
Probably worthwhile googling leather tanneries, tannery factories etc.............. avoid the word 'tanning' though you will get sun cream and holidays. In fact put ''youtube leather tanning'' in google you will get lots of video information............. here is a modern tannery https://www.youtube.com/watch?v=zbj1QicTdpI vs a traditional Moroccan tannery https://www.youtube.com/watch?v=MeuMcYB4BL8 here which is the actual one I visited (never again)
