I'm making decorations for a cake out of gumpaste.  Gold colored swags that will be made in a mold and placed on the top outside edge of a buttercream finished cake.  How do I achieve shiny gold from white gumpaste?  I have an airbrush, if that is an option.  Or should I paint it on with vodka and luster dust after the decoration dries?  Or do I paint on luster dust without the vodka?

Thank you for any help you can give me!

I think your best bet is to mix luster dust with alcohol and paint it after it drys a bit on the cake.  Using white gum paste to start is a good idea because I have had my colored (dark yellow) gum paste to bleed out into the cake, not a lot, but more than I wanted.  It would probably be best to have your gum paste the color of your buttercream, or as close as you can get it, to start.  That way your edges will not show up after you cover the tops with gold.

SandraSmiley,  Thank you for your reply.  Why paint the gumpaste on the cake?  Why not just do it days ahead of time?  

Another question ...  Will a gumpaste swag adhere to (crusting) buttercream, and not fall off? Or should I use some sort of edible glue?   I haven't made the swags yet, but they shouldn't be terribly heavy.

thank you,

Christina

If you make them in advance and they harden flat, they will not conform to the curve of the cake unless you have something the same size and curve on which to dry them.  In that case, it would be great to paint them in advance.  

I don't know if it is strictly necessary, but I always put a bit of edible glue on the pieces I am sticking to the buttercream (because it has already crusted).
