I live and dye(hahahaha) in DFW(Garland). The process may or may not take long. The better your process, the more efficient, but I have stencils that took me hours to cut out and 10 min to dye. I have also had stencils that took 10 min to cut and hours to dye. As I dye more my process becomes better. I think Dan Howard talked about taking notes somewhere. If you are wanting consistency easy, notes will help. Winging it works too, but may take longer and increases the trial and error factor.
I am up for a dye session in DFW. And I am close to Harry Meyers. Let's do this.
