AIm a novice home baker, im planning to make a barbie cake for my friend's little girl this saturday, I would like to know if i can decorate whip n ice with rose petal ruffled effect fondant? ( barbies skirt) Will it hold up well? Can i use edible glue to stick into the whip n ice? I dont personally like the sweetness of buttercream,

Thank you! Looking forward for your responses :)
