My hand skills are seriously lacking and I can't give you a hand answer.
Since I am using the machine, I am sewing through all the layers when I attach my french binding. That is the two layers of the folded binding, the top of the quilt, the batting and the back.
I use a slightly wider binding than most (cut 3") and I do not trim my quilt until after the binding is attached. (The top was squared before quilting) I use the seam line and trim 1/2", then flip and hand sew the back.
