I was given a beautifully constructed skirt, that unfortunately didn't fit in the waist. When I started to unpick the waisband I discovered a new way to make a perfect narrow waistband.
Step 1: cut your waistband 2.5" (6cm) wide (I interfaced with a very light weight iron-on).
Step 2: sew to the skirt front with a 5/8" (1.5) seam and then sew the other side of the band to the lining, using the same seam allowance.
Step 3: Only trim the seam on the lining side of the band, the fabric side is folded and pressed to the inside of the band to provide more support.
Step 4: Fold the band in half and sew in the ditch from the right side.
You end up with a beautiful narrow waistband with the lining attached and no hand sewing.
I have posted photo's of each step in the above link.
