Need help painting stitches without using the stitch brush

I have an old model I made almsot 10 years ago that had some military vest pockets with a lot of stitching that was part of the model from zbrush. I'm revisiting  the project and I baked my maps into my lo res, and now I want to find a way to get those stitches painted in an automated way. I can't use the sitch brush because the work is already done based off my hi res sculpt. Currently the only way I know is to manually paint on top of each stitch which would take forever. So if anyone knows a way to get those painted based on my curvature or normal map, that would be great.
