I made them for a play in which all the main characters were grownups playing children; the plot was completely from the childrens' point of view. As such, I wanted to make these "parent" puppets big, looming, and cartoony. Cecil and Cecilia were quite loud and obnoxious.
In making these puppets, I was drawing very heavily from the work of Erminio Pinque / Big Nazo Puppets, Providence, RI. (I hope to have pictures of his puppets up here eventually-- he has a puppet band that has opened for major rock bands all over the country.) He informally taught me the construction technique (sheets of foam rubber with a special paint), and how to use it, backstage at a play we were both working on.
I drew somewhat on the Bread and Puppet Theater for the performance style.
