 So you just want an easy way to make non-destructive cloth seams, not a problem. Now we're just going to use the basic denim fabric as a base, then add a fill layer. Hold Alt and Left Click to disable everything except for the height, increase it a bit, then right click and add a black mask, then right click the mask and add a paint layer. And just so we can see what we're doing, we'll just brush a few things onto our paint layer. Then right click the mask, add an anchor point, then create a new fill layer. Again, hold Alt and Left Click to disable everything except height, increase the height, then right click and add a black mask, right click the mask and add a fill layer, then click gray scale, anchor and pick your anchor point. And last, right click the mask, go to filter and click mask outline. From here, you can basically control how the seams of your areas will interact. If you have good topology, this works extremely well for highlighting things like pockets. And if you want to use stitch brushes to outline or trace over, you will get an even better looking fabric design. Hope that helps and as always, I hope you have a fantastic day and I'll see you around.
