Thanks to both of you for your nice comments. No, it is not an original design. I found it in a book by Pam and Nicky Lintott titled "More Layer Cake, Jelly Roll and Charm Quilts." It was called Double Nine Patch. Theirs was a little scrappier than mine, but the design was the same. I used the swap nine patches and then a jelly roll to make the borders around each of them. Not sure how to post a larger pic - tried but it was always the same size.
