Reply Tips On Achieving Crisp Edges with Fondant?

For buttercream, if you use all butterand no shortening to get it to firm up in the fridge won’t it melt when out of the fridge even if covered in fondant? I haven’t tried the ganache and would love to soon but I use buttercream all the time. I find that even if my frosting has hardened or crusted, once I put the fondant on it just shifts all underneath and doesn’t stay put!
