I see all these beautiful cakes with luster dust in the frosting or the fondant. Where do you buy the luster dust? Can you only use it in fondant or the regular buttercream frosting? I'm anxious to experiment with this but can't find it. Please help. Thanks.

I get my luster dust from a cake supply store. You can mix it with grain alcohol or lemon extract and paint it on fondant. I just recently read a reply that said you can mix it in buttercream. I don't remember who it was though.
