If I am going to machine sew my binding, I do the Quick Machine Binding with flange method posted by Charisma. I match the thread colour when I stitch on the flange to the backing fabric so it hardly shows.
I wish there was a way to machine sew the binding on the front, flip the binding to the back and then straight stitch in the ditch from the front BUT when I try, I always end up with a less then perfect result on the back.
