I am glad you like Elle's center ... and, don't be intimidated ... I am thinking that a round robin is a little bit of the owner, and a little bit of each person who makes the rounds.
When I did the flying geese units, I had considered that the flowers needed something more angular/structured than organic, and when I took it to a quilt shop, the lady who helped me said the same thing IMMEDIATELY! So, I was pretty sure we were on to something.
Having the same batik in a different color family sounds very intriguing!
And, I am glad to know that you are reasonably new to quilting because I have some other things <g>.
