I put my binding on by machine. I always use a walking foot, sew the binding on the back first (sew line is 1/3 of the binding), then pull binding up and iron up, and then pull the binding over to the front and sew on the edge of the binding. While attaching, pull the binding over to cover the sewen line (a little beyond the line because when you release the fabric it will slide back anyway). I never have any problems, I don't even pin or clip. As a hint, use the same color binding as the back, then if the back is not exactly even, the threads just seem to disappear and the front looks perfect. Good luck!
