Hi! i was just wondering whether it was worth investing in a premade flower paste for making 105mm sunflowers for a wedding cake i have coming up. I attached a pic of a practice cake I did and the sunflowers were made from fondant with gum tragaganth added and they were hard but brittle and im not sure if they would hold their weight indefinitly. i also find it really hard to get this fondant/gum trag mix to roll very thing without getting stickly and tearing so the sunflowers were very heavy and that also worries me in regards to getting them to sit of the cake - any ideas??

for the topper I pushed the wires from the flowers into a ball of fondant on top of the cake. Is this the best way?? any other ideas? Also, what about the flower on the bottom tier, how could i attach it firmly, in the pic it's just set on.

Please help, im pretty nervous about this cake due to the sheer size and weight of these flowers - should i try a different medium to get them thinner and lighter?
