I understand the basics of fondant... no problem when it comes to something convex like the basic circle or square, but I'm a bit worried that I'll run into trouble covering a petal cake with it's indents. Does anyone have any tips for me so that I don't end up pulling my hair out? I have the Fat Daddio petal pans which have 5 petals, and therefore have bigger indents than the Wilton 8 petal ones.
Since the indents aren't very deep it really isn't too hard to do. Just roll out a little larger than you would for a round that size and gently form it into the indents.
I just did it on the top tier of my tie dye cake...
It was really quite easy....just keep pulling out the fondant and smoothing into the petals as you go until you are all the way around. i didn't have any problem with it and I used the same pan that you have..
