A spectacular Las Vegas bakery creation, the Rainbow Festifal wedding cake is crafted with five stacked layers of unique shapes and fantastic patterns that are colorful, bright, and wildly designed. Each tier is uniquely decorated with swirls, polka dots, scrolling, ribbons with zig-zag edges, or wide bands of color. This is one of the boldest wedding cake ideas ever. This sugary confection is highly creative and deserves a wedding cake topper fashioned with just as much imagination.
