100% Blender procedural material.
Pure Material Practice in Blender, so the model is just 5 minutes work.
The material takes care of stitches, creases and leather look.
Stitches is done by feeling where the edge are and then adds a bump map to it.
Creases is done by finding center of an object and then add some noise with distortion and scaled a bit and then soften when it reaches the edges.
