I have a kit that I bought years ago on sale, all cut, that must be that quilt!! It doesn't have the black included, just the gradated colors. I didn't know what I was buying at the time, how funny. Its beautiful. Mitering is easy, don't fret. Easy to say, I know, each time I've done it, I still worry, and each time it goes together great. This past Christmas, I even did a striped, mitered border, so it had to be perfect for the stripes to line up. It went together perfect. You will do fine, and be so proud after!!
