The Prostheses Foundation and the Breast Foundation, both under the patronage of the princess mother, were two projects initiated in her later years. The Prostheses Foundation was set up in 1992, when she learned that a doctor from Chiang Mai University had developed below knee prostheses from recycled plastic bottles which cost only 700 baht, and artificial limbs that could be used for agricultural purposes for 300 baht. She saw this as an opportunity to provide artificial limbs free of charge to the poor. With initial funding donated by the princess mother, and further donations from her daughter, Princess Galyani Vadhana, and the general public, the foundation offers artificial limbs to the needy.
