I chose watercolor as a medium. Then I brushed and splatted and blew paint through a straw and spritzed with a spray bottle filled with paint. In some cases I used a stencil and added some decoration with a white gel pen or wrote using black archival ink.
Below I actually splashed paint on a baking tray, then gently laid the paper over it. After the paint dried, I drew with a white gel pen to lighten up the painting a bit.
I could create more and more ... but oops, the next assignment has been posted. Another fun one!
