I make and sell handsculpted rose earrings out of polymer clay, but I have always just used solid color polymer clay . I have just been contacted by someone who wants white roses with pink tips and I'm not sure of the best way to do this, so my question really is more involved then the one listed above. I do not have experience with using any more that one color of polymer at at time and I have never tried painting polymer with anything. I have heard of Fimo liquid though. Is that something that I should use and mix it with paint? Or should I just paint right onto the baked polymer? Do I need to seal it? Thank you for any help you can offer.
