When using any media to colour please use an A4 piece of paper to stop the substance going through to the other designs in the book.These designs derived from observing oil slick colour and the creativity that the oil colours perform. Have you ever watched oil in water and how it interacts with soluble matter. It swims, inter twines, moves and glides, whilst trying not to break up. When it does it creates a globule of rainbow colours when light hits it. My fascination became a work of art and then extended it to what is created in these therapeutic books today. The oil Slik art has been crafted into many different drawings, paintings and personalised to suit individual tastes. My daughter asked for a clown and Dolphin one. My nephew asked for a car and motorbike one. I, after decades of doing other peoples, have done my own. My design has opened up the heavens, literally and created ballerinas, stars, clouds, birds, dancers with ribbon and so much more. You can add any topic you want when you are ready to take the plunge into doing your own personal design. Go, go, go.
