Check out Judy Martin's Log Cabin book. I used this for my retreat a couple of years ago and it is one of the best quilt books I have ever purchased. It has the uneven log cabin blocks in as well as many other patterns AND a number of different layouts. The reading alone is worth the price of the book.
I have a couple of extras of this book on hand. If you are interested, please send me a private message and I can let you know about purchasing one.
