What do you do when you don't love the fabric you picked for your quilt?

 What do you do when you don't love the fabric you picked for your quilt?

I rearrange and rearrange but I'm just not loving my fabric picks for my rainbow quilt.

Too many brown and maroon tones for my taste so I'm seeing if I can exchange (I purchased precut bundles).

If I can't I'll try pulling out the fabrics I don't like, seeing what I'm left with, and filling in from my local quilting shop as needed.

At this point I'm updating my plan from 3 inch squares to 2 inch squares so each 12 inch block will have 36 fabrics. I love rich detail like that.

I'm also debating between using large 12 inch squares of the same fabrics on the back or using something totally different like a white on white print.
