I am doing this cake for my daughter's wedding. How many petals do you think I would need it will be a 3 tier. She wants the plaster buttercream look, what would be the best way to attach the flower and petals to that? Also for the main rose should I do it with a wire? Hope the pic shows if not it is a rose with cascading petals.  Thanks!

You might find info in this thread:

ACan't you just count the petals? I'd do the rose on a cocktail stick so you can poke it in.

Looks pretty easy to guesstimate, or count them.

Thank you, the video helped alot

Think I know the answer however I always have to ask to make sure. For the above cascading flower cake to make the flowers/petals...half gumpaste, half fondant for less breakage?  Also royal icing to attach to the fondant? This cake has to travel about 12 miles I do not want any to fall off. I will take extra along just incase

thank you in advance

Royal icing will not be that much of a help & just one more thing you will need to make.    Personally I'd just stick them in a somewhat thick coating of b'cream (if the cake is b'ced).  If you are covering the cake in fondant then you would need some gp glue or paint each petal (just the lowest parts that will touch the cake) w/a tiny bit of water.  A 50/50 mix of gp & fondant is fine.

Thanks for your help.....yes the cake will be fondant covered, that is why I thought the royal icing would be better as it goes really hard no slipping of the flowers as I travel. Although the gp glue (which will i have never used) will go rock hard to hold the flowers right?  I hear white chocolate is also good to use.

Tylose glue will go rock hard, but there's a minor learning curve with it. Basically if you paint some on and let it get tacky for maybe 30 seconds to a minute, then things will attach easier. If you use too much, it will not attach and keep sliding. I would use a medium wooden skewer for the main flower (not a super skinny one).

But there are going to be spaces where you may need something that takes up more space than the glue.

I've never done this design, but other than the main flower part,  I'd be inclined to cut the petals the day I'm decorating the cake. As they become dry enough, apply on cake while still firm, but still have a little give. Or at least make some of them with having in mind that some extras will be needed. At least that's what I'd do to achieve the look of that particular cake because you can almost see where the pressed the petal centers into the cake.

I might try to make most of the ones on this cake ahead of time.
