Very Pretty, is this strip pieced?

I can feel the warmth it gives off! It's beautiful.

Cool, it makes me think of solar flares!

I would like to thank everyone for all of the wonderful comments. I called my son to share your many encouraging responses. He, too, is proud of this quilt. Now, I am finishing an outfit that I made for my little granddaughter and designing a quilt for my other son, who recently received his Master's from Michigan State. I'm new to quilting, but not new to sewing.
