I've got 2 DVD's:
"Getting'em Thin" by Roger Warmuskerken
"Rattlestick: A Selfbow Turtorial" by Gary Davis
and 2 books:
"Flintknapping: Making and Understanding Stone Tools" by John C. Whittaker
"The Art of Flintknapping" by D.C. Waldorf
I'm mainly looking for vegetable tan leather (8+ oz.) and/or rawhide. These are going to be for knife sheaths, so I don't need huge sections.
