In looking at it, you have the gold going different directions. Also you have the blue centered patches side by side. I would use the gold patches in all 4 corners and one in the middle, all going the same direction, then use the blue center patches to fill in. It would be great to use a blue thread on the gold to tone it down, but to enhance it by quilting it like ends of a flower. I would not use sash strips. Of course, this is only a suggestion. I love the colors.
In looking at it again, try putting the gold strips all in a row. That way it would come down the quilt from corner to corner. Then try it with the blue ones from corner to corner. Every time I scroll up to see it, I see something else.
Now I see a bowtie from corner to corner with the plainer patches. I would use a small gold border to start with, then add a larger bright flowered one, ending with the blue border. Thanks so much for showing it!
