my friend's birthday is tomorrow, and i've called all the nearby bakeries, but none can do a hello kitty red velvet cake... and since red velvet is her favorite kind of cake, i figured i'd make it, but i want the Hello Kitty design on it. How do o make a design that looks like the kind you'd get from a grocery store or a bakery.. like it's airbrushed? or at least, how do i make the frosting lay down so that it doesn't have all that texture to it?

just, how do i put the frosting on so that it looks professional???

thanks a bunch in advance, i know the question's kinda all over the place...
