The wet application is perfect for when you want an opaque finish that really transforms your cookie into silver or gold. These First Communion Chalice cookies are a great example...and the tutorial for applying is there for you as well.
Adding the luster dust dry lets you see the original cookie color, but adds a sheer, metallic shimmer.
It really couldn't be easier. Let your cookies dry overnight, then use a clean and dry paintbrush to brush on the luster.
How about now?
The same luster dust color I used here can be found at Sweet!
