I am trying to make a baptism cake for a friend, she wanted a buttercream slab cake with a fondant blanket laid over it (flat, not bunched up).

I tried twice now, first time my blanket stretched all out of shape and I had to start over....second attempt my blanket got bunched up while trying to get it on the cake.

Any tips on how to roll out a blanket and lay it over a cake without it stretching or bunching up? (just so you know, I don't have one of those large rolling pins, wish I did!)

roll it out on something, a mat, plastic placemat, etc and then flip it over onto the cake (it should be something flexible that you use to roll it out on) htm

Do you have a tall glass bottle? works just as good...HTH

Try folding one end towards the center, then the other end toward the center, pick up with a piece of cake board, slide it on to the center of the cake, then unfold.
