i have been working on my neices cake all day. it was making starts and heart to stand up off the cake and I was using the buttercream fondant (which I always use) and it's not wanting to harden. if anything it's getting softer as it sits i'm not sure what to do I was also wanting to make some curly ribbon type decorations for it too but they're not geting hard either. if there something better to use? and better (and very easy) fondant reciepe, gumpaste, molding chocolate, something?!?! help please! please, please, PLEASE!!! TIA

Simple marshmallow fondant with some gum-tex or tylose kneaded in would probably be the easiest...melt 16 oz marshmallows and 4 tablespoons water in the microwave, stir in 2lbs powdered sugar until it gets too hard to stir, turn out on greased surface, grease hands and knead until smooth

It will harden overnight. You can add tylose or gum-tex to make it harden faster, and to make decorations on wire harden faster, instead of dipping the wire into gum glue, heat the wire in a candle flame for a few seconds then push it into the fondant.
