Being a complete newbie to any and all of this I need to ask a question. This is completely my first ever attempt at making a costume for anything so I'm a bit overwhelmed and confused. I see everyone masking off the sole of the shoe and leaving it black. Reading through the requirements for the ROTJ for level three (still unclear what all that means), It states the soles must be white. Does that mean the whole sole, or just the visible part on the outside? Also, why am I not seeing everyone painting that part as well? And once again......read more! Figured out my mistake.
