Drawing Lab : Lab 1

I am currently going through a new book that I bought at the Sunday Fremont Market. The book is Drawing Lab for Mixed Media Artists : 52 Creative Exercises to Make Drawing Fun! by Carla Sonheim. You can purchase the book from Amazon here: http://www.amazon.com/Drawing-Lab-Mixed-Media-Artists-Exercises/dp/1592536131/ref=sr_1_1?ie=UTF8&s=books&qid=1279729095&sr=8-1-spell

Here are some drawings of cats from Lab 1
