There are couple of things that I do as care and feeding of my creative process. First is keeping an idea journal where I constantly add ideas, in part to keep from the distraction of doing them. The second is to constantly experiment with materials. My latest experiments have combined iron metal filings with wax and a powerful magnet as well as combining wax with different expanding urethane foams with cutting them to look like a cross section of bone. Was going to use the bone underneath a cutout in a piece but I put it into photoshop to work out the concept and composition and now it looks too heavy handed. I hope that the R&D pays some dividends.
