Oldman-
Check out
www.crazycrow.com and
www.matoska.com for beading and quillwork books.
One I can recommend is "The Techniques of North American Indian Beadwork" by Monte Smith.
If you plan on using brain tan hides for the cover check out
www.braintan.com which has lots of resources and links.
Don't know of any specific books on Indian Contruction techniques.
