6
Stretch fondant easily so there are only creases hanging past the bottom of the cake board and none above the cake board. Your fondant should go past your cake board. The larger the piece of fondant, the easier it is to smooth. Fondant that barely covers the edges of the cake will most likely wrinkle and be hard to smooth.^{[4]

7
Trim at the edge of the cake board to remove excess hanging fondant. This is important not to trim it shorter because it will cause wrinkles when smoothing. Also, if it is left long then when you are smoothing the hanging weight will cause the fondant to pull away from edges of the cake.^{[5]

Start smoothing with a fondant smoother tool. Always start smoothing from each corner and work toward the center line of the side. Once at center line the start at the top and work your way from top to bottom. You can lift the fondant at the cake board to help release air and stretch a bit to pull out wrinkles.

Smooth the top and sides of the cake. Trim bottom excess fondant with a sharp knife, pizza cutter or a craft knife.

Question

How large a cake will 250 grams cover?

Community Answer

It really depends on how thin you roll it and the consistency of your fondant. Also, if you have a more intricate cake, you will need to use more.
Question

How do I get the corners of the cake right? It keeps breaking and the cake does not look smooth at all, even though I followed all the steps.

Community Answer

If it's falling apart when putting the fondant on the cake, it must be too thin. You have to make fondant flat, but paper-thin is not recommended if you're a beginner when using fondant. Once you get it right, just layer it on top of the cake as smoothly as you can with little creases, but creases are okay and easy to take care of. Cut off or smooth over excess fondant and be precise when cutting it so you don't make the layer crooked.

Warnings

Fondant that is too thick will not smooth well.
