For this background, I smooshed the paper into the inky water on my craft sheet, then picked up specific colors with a large brush to splash onto it. That worked pretty well in the absense of the distress sprayer.
I like your background with it's splotches and your sentiment piece. I'm surprised the oxide inks are out already. Looks like you've had fun playing with them!
This is beautiful! In a way, it reminds of alcohol inked background but more softer. I really like how you stamped over the floral image too with the sentiment. Great idea!
