I have been asked to do a 25th anniversary cake. They brought me a napkin and it is silver. Parts of it is shiny. They do not want fondant. Can anyone tell me how to do a shiny silver part? I figured for the part that is not shiny i can just use a gray color buttercream. I would appreciate anyone's help. I am clueless.

I once used silver pearl dust mixed with clear vanilla and painted on buttercream. Most people probably don't recommend painting bc, but I did it a couple months ago and it was ok.

airbrusing over a smooth crusting buttercream may work?!

There is some silver glaze by Bakery Craft I've not tried yet, but they have at my local cake dec. store. And I know s u g a r c r a f t carries it. You're suppose to be able to paint it onto the buttercream. If you didn't want to do that I would go w/ gray buttercream & dust it w/ silver luster dust.
