Nice quilt! Sometimes you will get a wavy border no matter what you do. My last quilt I measured across the middle in several directions, eased where I needed to, used my walking foot and all was good until I spread it out on the floor after hand sewing the binding to the back. Yep, wavy border. I think I need to remove the binding and pull it tight as I sew it to the quilt to pull in the edge a little. Am I going to pick out the hand stitching and re-sew the the binding again? Nope, I figure with all that handling and re-sewing it will just get worse. Done is better than perfect!
