How would I go about replicating it in Photoshop, possibly with a different background color than this gray-brownish one? Of course, it would be best if the pattern could be on its separate layer, so it can be compatible with any background color.
I've tried using the pen/pencil tools to draw some lines and then blurring them and reducing the opacity, but it never looks quite like this. Any ideas?
