In developing the E.P. sculptures, Disney artists refer to the original layout drawings, background paintings, and the film themselves as a starting point. Artists face a unique challenge when sculpting a setting rather than a character because they must envision unseen angles and viewpoints. For instance, no one sees the back of the White Rabbit's House from Alice in Wonderland, but the artists who created it for the E.P. collection had to imagine what it would look like from every angle.
Scale is another challenge.
Artists had to alter the scale of the gigantic tree that forms part of the Woodcutter's Cottage from Sleeping Beauty or else the entire sculpture would have been enormous. On the other extreme, minuscule details, like the tiny bar of soap on the Seven Dwarfs' washtub, were equally difficult to scale. The E.P.s are originally sculpted in clay, then cast in a mixture of resin and alabaster which is specially formulated to capture all the architectural details. Once cast, the E.P. are meticulously hand painted. Every piece is like a three-dimensional oil painting.
