It still bugged me there wasn't any of the added in fabric in the center so decided to take that apart and add some in. In the process I decided to take the dark purple out of the center and just use it as an accent strip between the center and the border. In the pic I just have squares pinned over the dark purple ones to see how it would look. Since I had to take it apart to take out the dark purple and add in the border fabric I also enlarged it by one square each way. With as many leaves as I have I thought it would probably look scrunched into the center space.
I have top and bottom border to add today and then I can baste and do the basic quilting on it before I start the applique.
