Ok so i am playing around with fondant now and was wondering a couple things.

1: How thick should the fondant be after rolled , max?

2:How thin is too thin?

3:how thick should the buttercream be under fondant (like a crumbcoat?)

Thank you

it's preference up to a point

#3 if you roll it thinner you need a thicker crumb-coat to hide imperfections and vice versa

#2 if it tears and shows too many imperfections it's too thin --prolly about 1/8 inch is thinnest possible

#1 1/4 inch give or take

Thank you, this helps
