Here is a source for cobbler's wax:

I've formulated it to be sticky without being messy from pine pitch and rosin. The white is similar to the wax made by James Leisenring. Both waxes are made by melting the ingredients and pouring them into water. When slightly cooled I pull the wax like taffy to toughen it. The cobbler's wax stains yellow silk to light olive and the white wax gives silk a nice gloss.
