I agree that you want a pattern that you can use a larger piece of your focus fabric - that print is so nice. Try adding some fabrics that read a bit solid ( like the first purple in the top row). I would lay the print with the purple, a charcoal grey, a black and a lighter grey. Then add in prints one at a time to see what balances it. I like the prints you are showing, but I feel the purple flower and the one at the end and several of the bold prints in the black and white are a bit overpowering for this great print. I would love to see a quilt with just all the fabrics in your black/white row. I think that would be outstanding!
