Abstract

A blade for a ceiling fan can include a first half and a second half formed from a pulp material. The first half is attachable to the second half to form the blade. Additionally, a blade can include a skeleton with an over molding made from a pulp forming the blade. Furthermore, a blade can be formed using a blade base with a pulp topper added to the blade to form an aerodynamic shape for the blade.
