When painting, animating or drawing folds I think of what type of fold it is; Spiral, Zig Zag, Half-Lock, Pipe or Drapery. They all have unique attributes and can often be found in specific locations.
I'm making a gown and decided to go with taffeta. In some lighting, it looks so cheep. In others, it looks very elegant. I know there's probably no way to dull down the sheen but, uh, would I be crazy if I tried taking some spray paint to it? lightly dusted over, and I'd patch test the scrap fabric, of course.
