I also would some sort of a "wobble stitch" over the seams instead of stitch in the ditch...don't know if you are quilting by longarm or by domestic sit-down....I had a quilt that I wasn't real sure of the seams.....so a quilted a rather dense "bobble" meander hitting every seam intersection I could on my long arm....I put binding on by machine and usually use a serpentine stitch on the front side. I have never had binding come loose dong this...
