I had to fold my sensei's indigo hakama before he left for a seminar.... and he NEVER folds it (he hangs it up after class). Needless to say, I had no lines to go off of. That definately brought out my CDO (CDO is like OCD, except in alphebetical order, like the way it should be)
Anyway, with a bit of diligence and patience, I got it looking nice... more or less anyway.
So yeah, I agree with you Kevin about folding teaching you something.
