You and Haley did a great job! It looks very nice. Congrats!
RE: geese border - I've seen on the home decorating channel that some borders pull off real easily and don't leave a residue. You should try pulling at a corner and see what happens. Or, my mom put a fabric border in her kitchen using spray starch to adhere it to the wall. Really simple. If you have some cute fabric you could cover the geese.
