I am going to decorate a gold layer cake. I was wondering if I should do glitter or confetti. I watched some videos that use coloured confetti then colour with lister dust. Need thoughts of what looks the best and easiest way to decorate.

just depends on the look you want to achieve and what you use -- because there are other methods too

Are you doing an inedible dummy tier or actual cake servings?

painting with gold and then brushing glitter on after makes it gold and glittery.
