Diamond Tufting in Leather ( Bicolor) Leather Upholstery

It is possible to combine two or more different colours when doing diamond tufting. As I show in this video I have used two different automotive leather(1. 3 mm thick) colours I had at hand. Suggestions: 1. To get a better outcome and ease procedure I would advise the use of thin (less than 1 mm)furniture leather material which is more pliable and softer than automotive leather. 2. I would advise the use a 7 cm (3 inches approx. ) dense foam as first padding then thoroughly cover it with a 1 cm softer foam
