Diamonds Chain Quiltalong Progress

Well, I love the design that Melinda did on the Diamonds Chain Quiltalong Progress.  I am very happy with the way the dye looks on my fabric.  I am also happy with my fabric selections.  BUT now I am having a little difficulty with layout.  I'll get there... I just don't have a specific direction right now.  Any suggestions would be appreciated.  Right now I have 23 blocks.  All of them are the same and look like this:

Here it is on the dyed fabric (pardon the wrinkles):

I wanted the layout to look like the negative space quilt here:

But when I do that it kinda looks like this and just doesn't look right.  (Don't mind the paisley color in the bottom right, that's the quilt on the bed now.)  I am also down to less than two yards of the dyed green, but I am willing to try to dye more.

I also didn't pay attention to how the white bars on the blocks should go.  I made all of them exactly the same.  I could either make more or rip some of these out to turn them to make corners.  I am down to less than two yards left of the dyed green fabric (I dyed SEVEN yards!!!)  I lost some to experimental blocks to other colors, but not that much.  I am willing to try to dye more.  I think it will match because I like the little variations here and there.

I could do the layout in strips with stripes of fabric between each row:

I think the spaces are too big and I'm not sure what color to use yet...  It will work itself out.  I still just LOVE the block!
