Research into wig making has produced varied results. I picked a few packages of inexpensive artificial hair to try out some of the techniques. The Tibetan lambskin sounds like the quickest way to make wigs & will need to find out where to purchase that.
Making shoes, now that is really interesting. Creating the upper portion in a variety of styles is very exciting. Making the soles will be a learning experience but well worth it to have such great flexibility in design.
