The effect you want involve some shadow comforming to the actual relief. 
Only an image applied is not enough. It may work for a specific 
orientation relative to a given light, but not in the general case.

You can actualy model the holes and relief of the stitching, or fake it 
using some bump mapping.
To get the best results, you'll need to actualy model each pieces of 
leather with the appropriate holes and stitching.
