You never know what will happen when you pull out the paints. The other day I grabbed some paints to use on a piece of cardboard I had prepped with gesso weeks earlier (lol!). I used a paper towel to blot off the excess water I was spraying on the paint. As I was blotting, folding, and blotting again I hadn't realized that something cool was happening.
When I was done I slowly unfolded the paper towel. I was totally surprised to see the cool texture and images that showed up just from the excess paint! I actually like the paper towel art rather than the cardboard piece I was working on!
You just never know what can happen in the studio!
