Nadine : well, optimism is create a center medallion square, for a rectangular quilt !
See what I mean ? Sooooo, I rumaged around this center square, with the beautiful applique flowers I had prepared and I didn't like the result. The "movement" was broken. Actually, the solution was just under my nose : let the fabrics "speak", use them as they are, let them take the commands ! (Why make complicate, when you can simplify ?)
I agree, finally it was easy.
I had also made some applique squares, which I could use for round three.
Up to now the result is pleasing me...
Next step : circles on brown background for top and bottom borders.
