i (like so many others) sew to front first-then turn to back for hand stitching;
sew the the back- turn to front- if machine finishing- this allows me to keep the front looking good, make sure it is all caught- i very seldom finish with a machine binding- if i do i tend to choose a decorative stitch of some sort for the front side stitching....generally i only do this type of binding for 'quilts for kids' quilts- because they request the bindings always be done by machine- since the quilts are laundered in industrial machines often- they hold up better/are more secure.
