I could not find liquid latex here and did not know how to make the hands. I posted on stopmotionanimation.com asked pros about the latex substitudes. I was suggested to wrap the hands with yarn(as it was shown on my previous post) and cover with silicone sealant. I am not totally happy with the result but at least I have hands that can be animated. isomer at stopmotionanimation.com also suggested me to paint with permanent marker but I was not successful doing that.
