Arts - Beadwork & Quillwork

At Black Hills State University one of the classes I teach is Traditional Lakota Arts which includes learning basic techniques of beadwork, quillwork, and featherwork. If you are involved in the arts and crafts, can you cite someone who was instrumental in generating interest in areas such as beading and quillwork? Most people started with someone who influenced them and lended a helping hand. Did this influence your style, designs and colors?
