Think ahead of how you want to decorate your cake and practice piping or icing ahead of time. You can easily make extra icing and practice shapes on test cakes (or even on silicone mats). Secure a wedding topping, flowers, or other decorative items well before the wedding. If you are using fresh flowers, be sure to order exactly what you want from a florist. Lastly, you will need to clear a large space in the refrigerator, perhaps taking out a shelf for the cake. You'll also need to arrange transport for the cake to the wedding venue. Speak to the caterer or venue manager about cake transport and refrigeration details at the event.
Once the marzipan is draped over the cake, gently pull down the sides to cover any gaps. Smooth the flat of your hand down the sides, pressing the marzipan to the cake and amoothing out any creases or overlaps, Rub the flat of your hand or a cake smoother over the top firmly to flatten and smooth the surface. Smooth out the sides in the same way. Trim off any excess marzipan around the bottom of the cake with a sharp knife and peel it off the board. This can be kept in an airtight bag or container for use next time.
