You Started Buy good quality brushes. Perfecting your strokework or in essence learning to control the brush is the basis for developing your techniques. Strokework is the foundation for creating beautiful designs, a great place to start. Select a paint that is suitable for the surface you want to paint on. The paint could be watercolor, oils or acrylics, the choice is yours.
Acrylics are less expensive than oils, dry faster and offer a wide range of ready made colors.
If cost is a factor, then while experimenting acrylics may be a good place to start. This is a very easy painting technique that creates a textural look similar to stucco. When applying the second color, keep reshaping the rag to maintain the creases that form the pattern. Lightly dip the rag in the paint, do not saturate and dab out any excess paint before you start. Then position the rag against the palm of your hand and, keeping hand flat, press paint onto the surface.
