The fabric is beautiful, but I agree that you need to iuse some calming fabrics between the busy ones.
You probably have your own methods, but I'll share this anyway. I often do a pasted mock-up of my paper pieced blocks --it is easy to pull off a piece of fabric and try something else (or just paste it on top of the original). For me it is a lot quicker than making up blocks. When I get it the way I want it, I post that one where I can keep referring to it as I am making the real blocks.
