I am working with polka dot patterns and trying to figure out how to make a grungy polka dot paper--so the dots aren't so perfectly round. I've been experimenting with a bunch of different overlays but I haven't been able to figure out what type of overly would do it. Does anyone know how to do this? I've already got a nice texture overlay on the paper itself. I'm wanting the dots to be grungy/imperfect.
(I looked in tutorials and didn't see this topic.)
