Hello all i have heard alot of talk about the BOOK dvd instructional guide. I have a couple questions for those who have it or seen it. There is 5 dvd in the collection. If you buy them individually at $29.99 as you progress or fork out $99.99 and get all 5 and save $50. My main question is i know how to carve and all the basics. Should i get the first 1 and 2 dvds to make sure all my technique is correct or should i save some money and just buy what i need. Also are they worth the money? Thanks and any comments is appreciated.
