This is why I make narrow binding. I trim everything even with the top. I cut my strips 2 inches wide, fold in half sew raw edges to edge of quilt using a .25 inch seam. Then when I fold over to the back and hand stitch it down I don't have ANY "flat" bidning (the binding that exceeds out past the seam allowance without anything to "fill" it) left. I taught myself to quilt, including doing binding and this is how I always did it! lol Maybe I have been doing it wrong all this time, who knows.
