Oh, yes, good call! Black frosting is bad enough, I can only imagine how much dye you'd need for fondant... and then the consistency would probably be thrown way off... and then your arms would fall off from all the kneading. hahaha
They're really very different techniques, so of course you're going to be more comfortable with what you're used to. I may attempt some fondant again soon, just for fun. But it'll have to be for my hubby or just some random cake that I make "just because" so that I don't have to feel bad if it turns out like my 5yo's play-doh creations. 😜
