I would rearange the pieces and not have all the dark on the bottom and mix it up,Think the gold is fine but just mix it up more.Just play with it and it will be ok. I worked in a florest and its like flower arranging,you can do round,triangles,onlong. Put it on a wall and keep arrangeing it.If you have to cut some off to fit in. Make your border fabric to make the center to pop, then add binding in same gold to finish it off. I can see it already done.Good luck. Wish I was there to help you.You can leave the gold in center but take some of the darker and put it with the lighter top pieces.You could take the sm light pieces of triangle that is next to the gold and replace it with the sm dark triangle that will match the different fabric patterns. Please show us how it came out. God Bless Dawn
