Long time ago, during the kinder garden years we learn how to make butterflies. To this day, this techniques is really dear to me. It is simple and it makes for amazing combinations of color and patterns.
The techniques is simple. Take a piece of paper, fold it in half, open it and place on which ever side you wish drops of paint straight from the tube. Once you have laid all the desired colors close the paper and press uniformly so that the colors can be transferred to both sides of the paper. And tada, that it is. Open the paper and you have a pretty and symmetric butterfly.
