I have an 18" round cake that I need to cover. I always find that when the fondant is rolled that big that when i go to cover the cake with it it is too heavy to lift onto the cake without tearing. Any suggestions anyone has would be appreciated as it is choco BC and ivory fondant so don't really want to mess it up.
You could slide it on to a large cookie sheet or use a rolling pin to roll it up like moving a pie crust.
I have a yard of vinyl that I roll fondant on then just turn it over onto the cake. HTH
I would roll it out on a mat and then flip the mat onto the cake and then remove the mat.
I would roll it onto the rolling pin, lift the heavy rolling pin over the cake...and unroll.
I would also recommend the rolling pin style and unroll it on to the cake. If the fondant is larger than your rolling pin, I have read that other decorators have bought long pvc pipes (the food safe kind used for drinking water) just for this purpose. I am planning on buying them too, if I ever get to do a large cake like that.
YOu can also do the taping method. Cover the sides with a roll of fondant.
