Here's what I did! I made the blue velvet cake replacing some odwalla blueberry smoothie for some of the liquid and then amped the blue value up with a little sky blue wilton food gel (this way I didn't add a whole gallon of just food coloring - yuck). As blue velvet calls for, I added a couple tbsp of cocoa and voila! A beautiful blue batter which baked into yummy cakes.
For the blue shoes, this got a little tricky as I had to make my own cookie cutter. I cut up the sides of a sturdy foil lasagna pan and then shaped a shoe out of a strip of foil. Because the foil was a little creased, I did need to smooth the edges once they were cut out so it was a time consuming project - thank goodness I only had to make 36! Once the the shoes were cut out, I pressed edible pearls and silver balls in to make the flower. I made these a few days in advance so that the fondant could harden.
Cream cheese frosting topped these blue cakes off along with some edible pearls - so pretty!
