I always match my top thread colour to the bobbin so I would make sure the backing and front were both compatible with my thread choice. I think I would do an oval or circle outlining the embroidery and then SITD on the 9 patches. The feathers would be nice in the white areas. Angela Walters has posted several FMQ designs on youtube that would look good also. I am thinking Paisley Feather or Fern Feathers? Nice top!
