Hooray! I got to make a UNICORN!
The Birthday Girl wanted a Rainbow Unicorn, so I did my best.
The horn is made from gum paste wrapped around a lollipop stick and brushed with metallic luster dust. All other decorations are buttercream.
And before you look too closely, the tail actually fell off about five minutes away from my house, so I had to reattach all that frosting before the Birthday Girl saw it! Just when I think I've got this cake thing figured out...
