I made this for my daughter's princess themed 1st birthday. I used a combination of instructions from CC'er msauer, some stuff I found from the internet, & looking at the wilton castle set that came out in 2007. I made the walls about 3 weeks prior to her birthday to allow plenty of time for them to dry b/c I ended up being sick the entire 2 weeks before her birthday. I got better about 2 days before, which explains the lack of elaborate decoration that would have otherwise been all over the cake.
