I removed all of the wimpy blocks, then took one row off the left side and one row off the bottom. It looks better already although I can see a few blocks I want to move. It would end up 56" x 72" without a border with this many blocks.
Yesterday I finally made a decision about the binding on the wonky rainbow quilt. I used the same fabric as the outside border. I have 3 sides hand sewn and sewed on the hanging sleeve before I quit for the night.
