Embroidery mockup file

I would like a photoshop embroidery mockup file which can be used to generate realistic embroidery images for logos and designs for polos. The main point here is that it should be very realistic when placed on logo or t shirt, and not just look "digitized" which seems to be the issue with most mockups..
The idea is that from the point of view of the viewer, the image should look like a embroidered logo, and not merely a placed object. We can start with the image as shown on uploaded files.
To be clear, I'm not looking to create an embroidered image of one item. I'm looking for a mock up photoshop program which I can use to embroider any image as required.
