I couldn't decide on whether to make it MSD size so he'd be more accurately scaled to Alice, but in the end went for KID size, so it could be used as a Halloween costume in the future. I started out with Milo as my model, but didn't really like him in the role, so switched to David....
In those situations I always set up the scene inside so I know exactly what I need to bring outside. It's a good thing too, since the three tables didn't have enough space to accommodate the cakes I originally chose.
The basic scene set up on the kitchen table. The only real 'Alice' characters I had were Alice, a Mad Hatter, and some mice, so I just substituted various other characters. After all, who says that the Tea Party depicted in the book and movie was the only one they ever had???
