So I tried again, spritzed while wet, let some of it pour onto the craft mat, dried the cardstock using a heat tool, soak up some of the ink that was on the mat, dry with heat tool. As you can see below, I got some awesome watermarks.
Below was my final attempts. I rolled some of the Distress Stain on my mat and soaked up with cardstock.
It didn't work out how I wanted, kind of ugly and spotty, lol. I think I'll stick to either the traditional method, or distress stain/spritz/drip/soak method.
