hi, can anybody help me i'm new and want to work with fondant but don't understand the frosting of the cake? are you suppose to just crumb coat or ice regular than put the fondant on? thank you...

It works best if there is just a light layer of icing underneath the fondant. If you put very much on then the fondant will not lay properly or will wrinkle or bulge. The undercoat of icing needs to be smooth as well as making sure there are no bulges from any fillings before placing the fondant on. Otherwise, every bump and bulge will show. HTH
