I think, if I remembered it correct (ok, my memory might be fuzzy since
it was when I was about 5 years when seeing the batiking as the CHEAPest
way of dying quilts), in China, they just boil the clothes after dying to
get the wax floating on the water.  Of course, the cotton cloth can stand
the temperature.  I guess, you would have to use cotton cloth for this,
don't you ?                                            BeeSurgeon
