The description in Today's Word says cloth has to have areas "covered" with wax, but doesn't say how. The cloth fibers have to be impregnated with the wax to prevent dye from coloring them. The easiest way to accomplish this is to dip fabric into hot melted wax. But it would be hard to get a desired pattern that way. I just had an idea. A piece of expendable cloth could be dipped into molten wax, spread out to cool. Then a pattern could be cut from this when cool, laid onto the work cloth, then a heat lamp could melt wax from it onto the cloth beneath it. This would make it possible to achieve a desired pattern repetetively if desired, or varied as desired.
