Turn your current design on point, let it "float" so the current borders do not quite touch the new borders, use blocks in the corners made with what remaining fabric you have - perhaps in the same "compass-type" design, and add finishing strips and triangles around them. Then if you wish you could add wider borders on top and bottom to make the quilt rectangular instead of square.

Jan, would you explain what you mean by floating and the current borders "not quite touching the new"?

add a dark purple border around it all. ah yes, like Jan said!!!

Very pretty--love Jan's idea!

That is one gorgeous quilt. I have never seen watercolor in that application before. Thanks for sharing.

I would use another floral to match the center colors.

Can't see anything I'd want to change, looks great from here.

nice i think the on point solution is good

That would be great!!!

Looks Great! Unless you get more fabric, I'm not sure what to do! I'd Leave it as is!
