To neaten off the top edge of the frill pipe a small trail of smooth
shells using either melted chocolate or colored royal icing.
Add some small white chocolate hearts and ...
... some milk or dark chocolate ones to the sides of the cake.
If you prefer you could also use some cut out marzipan or sugarpaste
hearts instead or even some miniature heart shaped sugar cookies.
Here is the finished effect.
The top decoration used is a posy of cream silk flowers and green silk
leaves. Alternately you could make a posy of white chocolate roses, use
some fresh roses or write a sweet message instead.
