Now we are getting our hands dirty with the clay muscles to give life to our scrawny adopted manikins. My approach to the construction of these muscles was fairly crude. I began typically by vigorously taking my rolling pin to a large clump of clay and continuing until flattened to my desire. I would then use an appropriate tool to cookie cut a section as closely resembling of the image in the book. Often my eyeballing approach would leave me a bit short but thanks to the wonderfully easy to build medium of clay I could simply morph an additional pinch to my existing muscle, if it only were that easy in real life. My technique held out surprisingly well for the given muscles and held the mentality not to get too worked up over a uncooperative muscle or two. I just hope I can stay this strong in the days to come.
