Christmas Eve I'm absolutely I'm there! After making my granddaughter's 1st birthday cake, a fairy garden with mushroom fairy houses that I had lights inside of, I know I can do this one. Definitely on my "must do" list of cakes!
And because the do-it-yourself version looked too hard, here are the already made versions!
I found the website I *think* they sell them from, but it's entirely in Japanese...so not positive. Go see how awesome they are! (There is even one with a cunning little snail shell on it!)
I am in geekish raptures. http://www.geocities.jp/youkeepon/works-parts/k-lamp/k-lamp-main.html
