I like 2 1/2" for my binding. I also sew the binding on the front and hand sew on the back. I have a friend who sews on back by machine then sews on the front by machine with a zig zag stitch. She made it look nice. However, when I tried it on a quilt I did not do as well. I prefer handstitching on the back by far for me as I find handstitching relaxing
