I was wondering how u think this is done...ive thought about it for a while now and at first was stunned and was like " HOW?".. The only thing that comes to mind to me is they used a fondant tool to roll out the edges to give it a ruffle effect (not sure wat tool) but then just put one piece layered on top of each other?....but wouldnt it not hold shape or fall off?...please need advise would like to try it for a baby shower cake
