There are many faults or problems that can happen while decorating a wedding cake. Some are... * Fingerprints or marks get on the cake * Wrong icing / color / designs * Cake falls over, cracks, tips, breaks * Decorations break * Decorations are poorly made / don't look right * Decorations fall off / don't stick * Materials only cover / decorate a protion of the cake, not the whole piece * Cake does not work all together, does not work with other wedding plans / designs
