I hope whoever decorated this cake gets workman's comp for the carpal tunnel syndrome they got after hand piping every one of those dots. I'd say it's worth it!
My desk can never have enough rainbows, must have more cute!
I know that little origami stars aren't all that hard to make, but are you really going to take the time to make a whole rainbow of them? Probably not. WORTH IT.
Just try not to think about the fact that the rainbow is pretty much cat poop.
