3D Rainbow Cake

Our first rainbow cake, in 3D. We've been getting a number of requests for rainbow layered cakes i.e.: cake layers are tinted in 7 different colors of the rainbow, but this was our first request for a 3D Rainbow cake! 

Again, credits and kudos to the husband for coming up with an amazingly stable structure which allowed us to create a through and through hole for our gigantic rainbow cake meant to feed 60 people! it looks wayyyyyy cooler in real life, and we're absolutely proud of it! : )
