PLAYING WITH BLOCKS by Darlene Zimmerman
What could be easier than playing with color in simple blocks constructed of squares and rectangles?
 Use up scraps, precuts or buy fat quarter bundles to play with -- have fun with this pattern!
 Once you've made one, you will want to make a dozen. 
It is indeed as easy as Playing with Blocks
