I used an 8" x 8" canvas board for this, mixed separate pots of acrylic and poster colours with a little water, coconut milk and silicon spray, then poured a little from each pot into a separate pot and flipped this on to the board, lifted that pot and waited for the colours to mingle. Lastly I blew through a straw to create different shapes. It reminded me of a cave with a little stream at the bottom, surrounded by some flowers, a snake and other indeterminate shapes. Just having more fun.....
