The production of an artwork is processing knowledge in a physical fashion. And once you get involved in the physical production of ideas (outside your head), your are participating in divergent thinking - that is, things come into fruition, unbeknownst to you as you work on them tangibly. Be prepared for unannounced surprises and let the materials take you this way and that. Give yourself time, and enjoy the process.
In knowledge production I've heard say, there are no correct answers. There are only choices to be made, and to make a choice you have to take a chance.
