My son loves Star Wars, the Clone Wars, and wanted Captain Rex on his cake. I found a drawing of Captain Rex on the Clone Wars Website. I traced the drawing and then made a pattern out of card stock.
I cut the card stock pattern so that I could lay it on the Clone Captain Rex cake and trace it with a toothpick. After I got the design traced on the cake I just used Wilton decorating tip #16, the start tip and filled it in.
The cake was a huge hit and he loved it.
