Later I realized that I probably should have spritzed it all with a little more water to get the bleach working, but some of the larger granules discharged. After it was dried and then washed with anti-clor to stop the bleaching, then washed again, it looks like this.
I think those bleached speckles are reminiscent of sparkles on water. Maybe I can draw some inspiration from this piece of fabric. I think it needs to be something pretty simple.
Today when I was out at the new house I took a break from laying flooring in the utility room (yes, I am laying flooring. I am too OLD for this...) I walked outside to inspect the creek. It is running clear now and it was sparkling a little like my fabric piece. It sounded great, too. I wish I could get the sound of water in a quilt.
