re: How to make buttercream glittery or shimmer

Let your bc icing get hard and crust. Then using lustre dust and apply with a soft brush to your bc. It will make it sparkle. Try spreading some bc on a over turned bowl, let it harden and practice on it too see how much dust to apply to achieve what you want. Hope this helps.
