this one is always difficult as I’ve found I usually don’t start drawing the artwork on the final surface them painting it, but rather do concept pieces on a smaller scale then combine them together to create the final design. Traditionally this process can be done by hand or by the use of an opaque art projector to scale up projects or add elements. Some other ideas for this would be, if you can get your hands on a large scale plotter, you could potentially print your art, either onto the final work surface or onto matte frisked for transfer. This would allow you to design certain parts digitally, then combine them together on a computer prior to printing the artwork. Any other ideas for do g this stuff?
