So this Round Robin will be the death of me yet. Biggest PITA(!!) ever. It is.
I thought this next round, "put curves on it", wouldn't be too hard. I had a couple ideas, one of which was incorporating a sunburst (na, too much paper-piecing) and then when I drew it all out, a picture frame, curving of course, kind of came to mind. And it looked good. Hunted through, oh, a stack of books and magazines for inspiration as to exactly how I'd do this.
