I recently made one. At first I had grandiose plans with several of my favorite color cottons, but in the end, found it easier to use a square of upholstery remnant. Lined it and put a magnetic closure on the inside. I saw many that had zippered outer pockets, but didn't want the inconvenience, so I just folded a piece of fabric so the fold was the top, eliminating the need to hem it, and placed it on the front at an angle before sewing the side seams. It's a flat pocket for the room key or other cards. My advice is to wear it around for a day. I found that it was just a bit too long, and irritated my leg, so I came home and cut some length off the handle before its second use.
