How do you do the petals on this wedding cake? Do you have to make them ahead of time & dry them or do you put the straight on the cake the day of? Any tutorials out there for this? Thanks!

Here is the link to the picture (the navy blue petals). It is made by "Madisons on Main"...

They look like fondant petals I would put them on last with edible sugar glue but here's a video hope that helps

Yeah, you could do some of them ahead of time but they'd dry a slightly different color, so it's best to do them all at once.

That's a gorgeous cake!  I would put them on while they are still soft.  I think if you left them dry first you risk them not fitting right and breaking while trying to get them to fit.
