My daughter grew up with Rainbowbrite and she wanted a Rainbowbrite cake for her 32nd birthday. So I found a photo on line and used wax paper and traced it and I used smooth butter creme on the cake and then I used piping gel with a little black coloring to out line the pictures and carefully placed it on the cake, pat, don’t rub.

Remove the wax paper and you have a coloring sheet!

I used butter creme and Wilton tip 21 for most of it.
