When it's this scrappy I prefer mixing up the blocks. It's going to be busy no matter what but mixing you get a better distribution of more dominant colors. But, but, but for that to work best you need a design wall of some type and lay out the little blocks before you sew anything back together. I've
never sewn the little blocks back into a unit of four before seeing how everything worked, color distribution, etc. Never. And then I tend to sew them into rows then combine those. Just apparently the way I like to work.
I'm wanting to make a medallion quilt of some sort. It has a bigger central motif, either pieced, appliqued or a printed panel. Then you build various borders all around it. A bit different than what I typically do. That could be your next quilt.
Forgot: for the design wall you can use a flannel sheet or flannel backed vinyl tablecloth. The quilt shop uses 4' X 4' foam core panels covered with Warm and Natural batting. Nice and sticky, easy to pin to.
