Your quilt is absolutely lovely! I like the border fabric on the right (the large print) and the way it pulls the colors out. Here's a suggestion...how about using some of the flowers as an applique broderie perse border on a light background?

I like the small flowers. Very pretty.

I am in agreement with the other comments for a solid border. But putting a pinwheel in each corner would give you that floral border interest you are going for. I really like this quilt.

Sometimes a quilt just waits for completion because maybe we realize we need to acquire a bit more skill before we can finish it. This quilt is just amazing in color and scope.

That is a fabulous design. I like the boarder with the large flowers.

What a wonderful pinwheel quilt. What is the size of the pinwheels? Would like to try this myself.

What a neat pattern. I also like the smaller print. BrendaK

that's really nice Ube, great use of colors

Unless you want it larger, I'd just bind it and be done. It's so awesome as it is, it doesn't really need borders.

I would either use a narrow black border, or perhaps a narrow gray border and then the bind it in black. The pinwheels should be the focus.

Far too pretty to sit all alone in a box unfinished and unloved.
