I received the message that the U. S. government is hiding knowledge about what is beyond Earth's atmosphere. But all governments hide information from the masses of their people. What intrigued me was when the Sentinel Prime character said to the Optimus Prime character that they used to be gods and now they were called machines. I can relate to that statement. I am a descendant of a people that were performing high sciences at one point in time and now we are beasts of burden. Try to talk to a typical African person about science and see what you get. At best they'll say, how does this help me pay my bills? At worse they'll look at you like you have 2 heads.

After trying three different sizes,I still couldn't find one that fit. I first ordered a medium and it wouldn't even come close to hooking so I went up to size to xlarge which was waaay to big, my last possible option would be a large and it was still huge, wish I would have sent it back but was just tired of the whole process and kept it. The hooks are a pain as well and it is way over priced.....there is a zippered option on amazon that is much cheaper.

I liked Ms Woods book on life drawing (which I bought through Amazon) so when I saw a DVD also listed, I was interested. Amazon listed it out of stock, but I managed to find a copy. I am amazed to see months later that you still show it out of stock. It is an excellent DVD. I particularly liked the way Ms Woods demonstrated each technique on paper rather than describing it, all the time showing the model, and at times even superimposing her drawing over the model to make a point. I found many of her 'lessons' helpful and would think many Amazon clients would agree. Incidentally, her book that piqued my interest wasLife Drawing: A Journey to Self-Expression
