i just looked quickly at all the blocks and it seems as though the blocks are all available ones in the public domain. if you go to the website given by ghostrider, you'll have the layout and the blocks all ready to be set up for you.
unless i'm wrong, i don't think you really need the book. with a little research you could probably find the block patterns yourself. many of them are on quilter's cache. if you're not familiar with that site it's:
http://www.quilterscache.com
have fun :wink:
edited to say: in answer to the real question: some of the blocks are quite easy. others are for advanced quilters. don't let that stop you. if you go at it, you'll become an advanced quilter.
