Ok, I've read through some of the comments but not all, so sorry if this is a repeat- I'm having a problem with the layout a little bit. For me, it needs a bit more order and symmetry. I see that there are four blocks that have large brown squares- could you use one of each of those in the four corners (and aim them in directions that make sense with each other- all aiming in, or out, or something), then somehow alternate the pink and green blocks throughout the rest of the quilt?
I really like the green in the first picture.
This is going to make a very pretty quilt, but, yes, we all have projects that just aren't doing it for us. Sometimes you just have to take a break and come back later. Oftentimes your subconscious will figure it all out for you and will present as some great idea that you never would have if you'd kept beating your head against the wall. Nice when that happens!
