I don't use any gadgets and my bindings come out great. What I do is I press one end of each strip at an angle. Then I glue baste the strips together and sew them. I fold the long strip in half and press. Sew to the top. When I get around to the end, I open out the end that I pressed, overlap the ends and mark where to cut using the measurement of the original strip as the overlap amount (i usually use 2.5"). Then I refold the end I pressed, tuck the other end into the fold, glue baste, sew the angle and sew the strip to the quilt. Comes out perfect everytime.
