Someone once told me I was obsessed with colorwash. I prefer to think I am driven to create with a smooth blend of values. I used to cut kits of 2.5" squares when I taught colorwash classes. There was usually a piece left by the fold from which I could cut a 2" or 1.5" square. If I cut a 1.5" square the leftover was 1" and those are the pieces I used for this little quilt. The 6" ruler is to give you a perspective of the size of the piece. I know I still have a tray of 1" squares in one of my storage boxes.
