In separate pots I mixed various acrylic colours with PVA glue, water and a few drops of coconut milk hair serum, then poured lines of colour on to a 6" x 4" piece of glossy photo paper. I poured a thicker line of dark blue along one side then, using a damp piece of kitchen roll, gently swiped this over the other colours to see what shapes appeared. I then swiped again over one corner to make an impression of coloured rocks and plants under the sea. Still having fun ....
