I love this project and have been doing these today with alcohol inks. I paint gesso on a sheet of bristol paper, but card stock would work great too. After it's dry, I take small felt pads on a stamp block (made my own with sticky velcro & an old block) and blot and rub the colors where I want it. Then it's time to doodle! This is not expensive, which makes it a fun craft to do with kids. ;)
