I press my bindings in half before sewing on. I cut strips WOF. I have never used bias binding.
I use to baste the edge of quilts before applying it. Now I use an old rotary blade and cut all layers straight, skipping the basting. My bindings look very nice. I sew on back, then machine sew on front. Looks great and easier on my hands.
I have made at least 350-400 quilts.
Different things for different folks.
