H, i have ust sarted with the wilton classes and i love, until i got at a fondant class , with i love too, ut my cake never came rigth, don't know if is the cake, the filing or me, my decoration is always beautiful, but never came out perfect round or square, i need some tips for that, because my last cake was 2 tiers round and the top one loks like a ball and not like a circle round cake. please help me .Thanks for now.

I'm assuming you're leveling the tops of your cake , so probably the reason that your round cake came out looking like a ball was that you pushed on it too much while you were smoothing it.

It just takes practice, especially the square ones.
