Quote - After watching the tutorial video for  that first product (the actions), it seems to have embroidery brushes included that are used in the actions and are edited a crap ton. 

Yes, thanks, lately I got info about a similar technique of multiple stroking contours. It seems one should fill the whole shape or text with black or any solid color, select it, make it a new contour and stroke with any chosen brush (it may be X-shaped brush to imitate criss-cross embroidery or a slant () stitch). As a result it produces stitched contours and the black core, which must be selected once again with the magic wand (if the brush is wide, the selection may be shrunk by few pixels), turned into a new layer and the whole process must be repeated again until all the shape is filled with stitch strokes. It's a bit slow but I tried and it works. It may be the source of actions, I think. Maybe when I find a good natural-looking style for realistic sewing stitches, I'll make my own action, though simpler, of course... It makes an effect of handmade embroidery, it looks in 3D software a bit more realistic than machine embroidery designs, made in professional embroidery software (Web is abound with such pictures, but they look often as simple beveled text). Thanks for advice.
