Embroidery effect

[joanna_kulpa]

Hi,
I'm trying to acheive embroidery effect on fabric. I need to do it in the most effective and simple way. For now the only thing I came up with and tried is I used a photo of embroidered pattern, turned it into bump map and applied to texture (which was a pink texture of the letters with transparent background; 0,5 mm from the fabric). I'm not happy with the effect, doesn't look good... Anyone has ever done it? Any settings suggestions? I wish to do it without the need to have photo of the embroidered letters...
My try:


What I want:

It presumably requires quite a high reflectivity but more importantly an anisotropic effect (which would stretch the reflections in the opposite direction of the stitches). Like hair.
