This is called Chained Lightning. Design by Pat Campbell. I purchased the pattern at e-PatternsCentral.com
This is paper-pieced. If I do another one I will use the lightweight paper that you can leave in for stablizer. Quilting it was a pain, I will keep this for myself - I am not happy with my quilting. I trimmed up some of the edges after sewing the binding on the front, nothing major, wasn't paying close enough attention and ended up cutting the corners on the binding, which I discovered as I was hand sewing the binding to the back. We live and learn by our mistakes. I still love the colors and will probably use it.
