Okay, I got said book today in the mail, and I need to know some stuff. I've read a lot of different things about it, so i gotta know, is the book good to learn from first of all. Second, I don't really have manila paper or a canvas thing to hold up drawing paper like it says I should have. should I get one, or can I just draw in my sketchbook? and about the contour drawings, the schedule says to make 1 drawing with 30 minutes. I can't do that! These things take like 5 minutes at longest, and there's no way I can draw one thing for an hour! So anyone who's familiar with this book, got any tips? thanks.
