I can't tell you how many times I have done cakes for the first time that I was so disapointed in. You know you have a wonderful family - you made that cake with love for your grandson, and he KNEW that. And THAT is what matters. There are a lot of Gramma's out there that would not take the chance - they'd rather play it safe and make everyone ooohhh and ahhh over something simple. YOU did what HE asked for, and he will remember that forever
. KUDOS to you, and I know you will kick butt on the next car cake you make for sure!
