I am so confused about when and when not to use highlighters. Everywhere I turn, the descriptions and info about use say they are not edible/should not be eaten and should only be used on decorations that will NOT be eaten. Yet, I see them used on piping and fondant and royal icing accents that clearly will be eaten. I fail to believe piping and trim painted with highlighters are scraped and picked off before eating.
I want to use highlighters on piping because it gives the most realistic metalic look. So, what do I do?
