I need to ruffle a 9" round cake using Sharon Wee's flower ruffle design.  Any thoughts how much fondant it will take just to do the ruffles?

Thanks

A LOT and about 4 hours of time. Hard to answer when we don't know how thick your roll your fondant. Do you use a pasta roller or roll it by hand - you could end up using more if you roll my hand and the strips aren't of equal thickness.

I do have a pasta roller. I am planning to roll it thin. Do you think 2 lbs is enough or should I plan for more? thank you for responding

 for me it took about 1 1/2 lbs
