I made a doll quilt this past spring that I just ended up not liking at all--and decided that the biggest issue I had was what you're talking about--tired of the fabrics, and actually I didn't like every single fabric I chose. I was only trying to use up scraps, which I learned is NOT a positive thing if I don't like the scraps to start with.
In looking closely at some of your fabrics, I'm seeing some that have shapes within that ==when assembled with others--appear to be running (the red one) instead of straight on the side. I also think the blue and white blocks are throwing things off.
If you are tired of the fabrics, you might not even want to mess with taking the thing apart. I wouldn't. I might keep it in the trunk of the car for an emergency or protecting things being hauled if necessary. I'm not saying I don't think it CAN be reworked but it sounds like you don't WANT to invest the time???
Live and learn. We all have visions that don't make the cut in reality ! LOL You are humble enough to show yours--I wasn't!
