I use a separate binding and machine stitch it , first to the back and then folded to the front and machine stitch in place. I really enjoy putting binding on this way, maybe it is the sense of accomplishment, knowing the quilt is finished. If I am using polar fleece without batting, Then I often wrap the backing to the front. I am not a person who enters my quilts in shows, so I just choose whatever works best. However, as someone pointed out, QOV need separate binding.
