I have been about to pull my hair out trying to make a mottle. Using paraffin, , paraffin with FO and steric acid, paraffin with mineral oil and FO, paraffin with steric, FO, mineral oil and I might get a little blotch of mottle out of all these experiments. This is driving me nutso. I just can't get it right, guess if I want a mottle I'm gonna have to buy some mottling wax.I think I'm gonna throw the towel in on this one or I'm gonna drive myself insane. (and I don't have far to go)
