I'd probably take off the binding and then quilt as noted above. You've spent so much time in making the quilt, just take the additional time to make it last. I spent last night undoing machine-sew binding on 1/2 a quilt because I didn't like how it was turning out with the thread I selected. I know it's a pain, but this morning, I feel so much better about the quilt (but sore neck)! I always try to live with "no regrets"........and I feel guilty not fixing things that I know about.........so for me...it would be worth additional quilting. Maybe you can try without removing the binding?
