Step 2: Fill with some filler flowers (like Dusty Miller) to add some texture. Use the icing to your advantage and stick the flowers into the cake to hold.
Step 3: Next move down to the middle and add some smaller focus flowers (Clematis + bud of a Ranunculus) as well as another sprig of Dusty Miller.
Step 4: Move to the bottom of your cake with a few bigger focal flowers again (Succulent + Ranunculus). This will create great symmetry with your cake.
