stitches in blender?

how can i make that material?
i know that el burjo de tribu has made a fabulous leather material and i intend to use it, but i can’t seem to find a good stitch texture, and one that is the same but as a normal map, but still so, should i unwrap it for the curves at the end of the watch strap?
but for starters, i looked for the texture, but i can’t find any! T^T
BTW, i only have digital watches, so can anybody help?
oh, i also want to know how can i make a material into a normal in blender (is that possible?)
