I need some advice about putting gum paste flowers on a buttercream sheet cake. I did a quick google search and found some say it's okay, and others say don't do it. I have to complete the cake about 6 hours in advance (or the night before ideally). Should I put the gum paste flowers directly on the cake or put them in some fondant covered foam? The flowers are on wires and they will not be standing straight up...more like a bouquet that kinda lays down...Maybe this is a horrible idea, but I am trying to avoid having to make a bunch of RI flowers...it's a half sheet cake.
Thanks in advance!
