Stitching on complex surfaces

Hi everyone, I’ve just started self learning grasshopper yesterday so I am completely new to this community.

I have been trying to mimic stitching on soft goods using the geometry in the first image by arraying them on curves projected on complex surfaces.

I have been able build the stitching geometry but have not been able to array it on the curves.
To be honest I have no idea how to proceed. I would like to be able to place them normal to the surface, tangent with the line at the point. I would also like to control the amount of the geometry arrayed.

The surface in the file is just an example I made for me to test. Ideally, I would like to be able to array the stitching on various curves projected on various surfaces.

It would be greatly appreciated if I could get some help and advise.

I’m an accessories designer and I’m also looking into this… This would be great for al sorts of accessories or fashion for that matter.
