As promised.. here's the pics of the cakes (plus a little extra). I ended up using all homemade frosting and my piping bags. I much prefer using the pre-made icing tubes that I linked to earlier in the thread.. but they didn't have the shade of pink I wanted. I ended up buying Duff brand gel colors. We went with "electric pink", "electric green", and "electric purple". The white-ish shade is the color the frosting is before adding color.
And now that that's done and over with.. on to school!! :D
