what size did you cut the binding? i do 2.5"
then after teh front is sewed on, i press it up and away fromt he quilt..all the way around.
*then i use elmers schoold glue for the back side, doing it in sections,and then press it down with iron/steam.
you can skip that step if you want to.
once the binding is pinned or clipped down..i turn the quilt over, and use the "stitch in the ditch" foot and run the stitch line down the original stitch on the front. i use a straight stitch.
it almost always catches the back all the way around. without it looking bad.
i can't hand stich anymore..carpel tunnel.. this is what works for me..if you need visual. i can take a few pictures for you..
