Not sure if this is the right place to post this, but here goes.
I made my son's 3rd birthday cake yesterday (a tractor) and decorated it using pre-coloured fondant icing. Following the instructions from the book, I rolled one piece of icing to cover the tractor. I found it impossible to get a smooth finish around the shape. There were bits which I needed to cut where there was spare icing (e.g- on a corner), but the join is still visible.
How on earth do you get the seamless finish you see in books? I used a smoother thing, but that didn't get rid of the joins.
I am pleased with the cake as it was my first real effort at something 3D, but I can't help being a but disappointed with the finish.
