Nowadays, non-photorealistic rendering is an area that not only focuses on simulates what artist do or the tools they use, but also on generates new expressive tools for digital art. In this paper we present a new algorithm to generate beautiful stippling illustrations with felt-tipped colour pen from a photograph or an image. This technique is not actually used by artists because technical limitations, therefore this new algorithm might be helpful. We introduce a novel stochastic approach to place coloured dots in a specific order based on the information of the contrast, borders and histogram of the input image. The system is able to generate an unlimited number of non regular synthetic colour dots without the necessity of being scanned. These dots will be composed in a specific order to generate the final illustration.
