Eco-sculptor Jason deCaires Taylor shared this video demonstrating his method of creating one of his full body castings that he will later add to his underwater sculpture garden in the Gulf of Mexico. Though he does use alginate for some of the detailed areas such as the face. Most of the mold is made of cotton scrim and plaster. You can read more about Jason's work in the Jun-Jul issue of ArtMolds Journal - The Artists' magazine.
