Remove buttercream leftover from the fridge.
Cut 3 cardboard circles, 25 cm, 20 cm and 16 cm.
Spread some maizena on top of the counter.
Roll down some sugar paste, enough to cover the 25 cm cake. To place on top of your cake do not use your hand but the rolling pin.
Use then the sugarpaste smoother and cut around with a pizza wheel.
Do the same thing with the two others cakes.
For the structure of the wedding cake, take the 25 cm cake. Insert one plastic dowel, mark with a pen. Remove from the cake and cut 5 pieces. Place so they will support the weight of the 20cm cake. One in the middle and the four others around.
Do the same with the 20 cm cake.
Place the 20 cm cake on top of the 25 cm cake and the 16 cm cake on top of the 20 cm cake.
To hide the play between the cake, place some orange ribbons and finish with your butterfly using some food glue.
