I use straight stitch... I always sew the binding to the FRONT of the quilt, and then turn it to the back and pin pin pin... I go around the edge, pinning right at the ditch on the front where the stitching will be. Then I peek around back and see where that pin landed on the back of the binding. If it's too deep or two shallow, I adjust so that stitch in the ditch will hit perfectly on the edge of the back binding. Lots and lots of pins. My fingers 'know' by now how much to turn and pin, and I don't make too many adjustments.
I never use glue on a quilt-- UGH.
When I sew, I sew slowly and pull the front binding away so that I can snug my sts up into the ditch. Then when the binding relaxes it covers it and is invisible from the front. My aim is to catch just the edge on the back, and not too much. If I have missed any spots I go back and re-do those areas. I usually have a couple...
