Rainbow Granny Blanket...Not Yo' Granny's Granny Square

Somewhere in the beginning of my endeavor to keep my hands busy in order to stop smoking, I had a flash of creativity and wanted to make a rainbow afghan. I knew exactly to whom I would gift the treasure and prayed over them the entire time I have been working on it.

To begin, I purchased one skein of Michael's Impeccable yarn for Red, Orange, Yellow, Green, Blue, Purple and Violet. I started by making a Granny square and just kept making it bigger and bigger until it looked like I had used up almost all of the yarn. Then to finish it out, I single crocheted my way around until the yarn was gone.
