How many times have you tried to apply dry luster dust to a very small piece of fondant without it getting everywhere?
It's quite simple, really. I can't really remember how I came about doing this but what I did find out was that my toppers came out cleaner, shinier, and all around just neater without it looking like my six year old had a disco party on my toppers.
I'll begin by showing you how they look before applying the luster dust.
Once my toppers have dried I like to finish them off by applying some vegetable shortening (such as Crisco) with a small brush. Not only does this give the fondant a nice sheen, it also removes any corn starch or powdered sugar that may have stayed on your fondant. Then I take another small brush and lightly apply the dry luster dust on the piece that I want shimmered. What I like about the shortening is that the luster dust adheres to the shortening quickly and you are able to glide the brush back and forth just as if you were painting. It really allows you to even out the dust without it getting clumpy in certain areas. If you take a look at the first pic you'll see what I mean. Certain areas look clumpy vs the image below looks as if you've use an airbrush machine.
And here is the finished product.
I hope this helps and thanks for looking!
