theres nothing wrong with that!! have a play about with pinks and red petal dusts or luster dusts but you have to picture it on the cake with the other lillies and foliage, etc. it will be lovely!
i'm afraid i don't have time to play and i didn't make extra in case i messed up (i know, i really should have...). the bridesmaid dresses are plum and i am putting leaves/vines on the sides of the cake to match the invitations. i am so bad with coloring and dusting!
