Hi Guys
One of the small microscopes is invaluable if you are not sure.
Faux Suede clearly shows a regular pattern with stitching, real suede is random and does not have stitching :

I cleaned some suede cushions last week, used a brush and spot cleaned a couple of stains with solvent. I ended up with cramp in my forearm after 90 mins of brushing, must be getting old.
Cheers
Doug
