Norman, my process is described on my website at

Ankhor, the cover was done for a publication distributed to members of our missionary group. We live and work communally and from time to time need to address issues that relate to different aspects of our life. This particular publication was about having a good work ethic and individuals "abiding in their calling." In other words, sticking to what they do best.
