This was a fun cake to make. The bottom tier was orange vanilla cream; the top tiers were lemon with lemon buttercream. I covered the cakes with sky blue fondant and then painted on a silhouette of the little boy and girl. I cut out 48 colorful gumpaste circles for the balloons. For the clouds I cut flowers out of white fondant and then rolled the "flowers" flat and into cloud shapes. Everything came together with puffy royal icing trim.
