My daughter loves rainbows. So for her fourth birthday there was quite a rainbow theme going on (see additional photos). She asked me for a "tall" cake in her type of rainbow. That meant hot, bright colors. So instead of red we had to hot pink. This is covered in MMF over single layers of each size cake. I didn't need enough to feed a wedding so I didn't do two layer cakes on each level. The bottom layer is just a 16" base covered in fondant. The 14" layer is actually rainbow rice krispies covered in icing and fondant. The 12" layer is rainbow cake. 10" had rainbow sprinkles inside. And the 8" and 6" layers were strawberry (her favorite). Not fancy but exactly what she wanted.
