i'm doing a cake using white fondant to cover the cake, i then want to give the white fondant a green pearl finish so i ordered the luster powder but i've never used it. instructions please?

Just put some of the dust in the lid and use a clean, dry square shaped paintbrush, to dust the cake. When you first get the dust on the brush just tap it gently to remove the excess and then use it. If you do not get the excess off when you apply it then it will have a darker spot that is difficult to even out. I don't know if you are using it all over or to highlight but, you can go back over an area to highlight it a little darker. Good luck.
