For this wooden coaster I mixed different acrylic colours in separate pots, added some PVA glue and a few drops of coconut milk, then poured a little from each into a separate smaller pot. I then flipped this on to the coaster, moved the coaster around to mingle the paints and helped create shapes by blowing through a straw and tweaking with a cocktail stick. The actual artwork is the coaster, the negative space around is just a piece of kitchen roll which I placed the coaster on in order to photograph it.
