I was playing around with some scraps today.  I had an idea, and I wasn't sure how it was going to come out so I thought I would do a test block.  From time to time I'll do this to make sure my measurements are right or to make a pattern.

It came out exactly how I wanted it to....but slightly boring and predictable. 

 

From the scraps came this.....something completely unpredictable.  Now I can definitely see the possibilities.
