Here are some things to check out that can help the novice flintknapper to learn the basics. In fact many of these sources will take you right on through to the intermediate and even advanced stages. If I have had personal experience with the source, I'll give a short review.
 
 

THE ART OF FLINTKNAPPING by D.C. Waldorf
After many years of wishing I knew how to make arrowheads, my father found this book and bought it for me. He also got a copy for himself because he had been longing to learn since he was a kid. D.C.Waldorf is one of THE names in the field of lithic arts. He has spent over 30 years studying the knapping process and in this book he shares what he's learned. Generously illustrated with photos and beautiful line drawings by artist Val Waldorf, you'll learn flintknapping basics like finding and spalling out rock, heat treating hints, tools, billet and pressure flaking techniques, and more.

VIDEOS

CAUGHT KNAPPING - Craig Ratzat
I love this video. Craig Ratzat has a knack for explaining things..and at just the right pace. This video takes you from quarrying material at Glass Buttes all the way to finshed points. Thorough examinations are made of tools, techniques, and terms. An example of Craigs great talent for bringing things into focus is demonstrated not long after the beginning where he shows just what a "cone" looks like. You couldn't ask for a better picture to keep in your mind of it's physical properties. You need this in your flintknapping video library. When I got my copy and found the surprise in the video case, I knew Craig was cool! You'll have to buy the video to find out what I mean.

Here is a very nice primer on how to heat treat cherts and other knappable stone the old-fashioned way.. by using techniques that were likely used by ancient knappers. If you can't afford a kiln then forge an even closer connection with those far away times by experiencing this method. Lots of other great information here as well.
