Paducah Nine Patch quilt pattern?
 

I just saw a gorgeous quilt in this pattern. It LOOKS like it is only 2 blocks could this be correct? If anyone can direct me to online pattern or instructions, I would be grateful. Also any tips on how it is made? The one I saw was very scrappy, just great. If it isn't terribly difficult, it might way-lay some others and move to the top of the list!

It's from the book "Nickel Quilts" by Pat Speth. It looks pretty easy, just four patch blocks.
