I don't worry about the backside of my bindings. I try to handstitch them to be the same size but, after the quilt is washed and dried I don't look that close at it. I have heard a full binding with perfect corners are what the judges look at the most. I have not entered a quilt show and don't plan to. Good luck.

i usually trim my quilt leaving 1/4 of batting past the edge of the quilt top to help fill in the binding when i turn it toward the back. if you cut your binding 2 1/4 instead of 2 1/2, you will get a more even look front and back. and no, it's not a no, no but it does look better if it is filled in more. good luck.

i am not sure on the actual answer. i try to line mine up with the stitching from the front. it seems to look really nice and the binding is one of my favorite parts to do on the quilt! it means i am close to be able to give a gift!
